For the numerical analysis of the time-dependent incompressible Navier-Stokes equations, several kinds of fractional step methods have been presented successfully However, there are still some problems about the boundary conditions of pressure Poisson equation. In general time-dependent problem with the open boundary it is difficult to prescribe the velocity itself on the outlet boundary, therefore in the conventional analysis those boundary conditions which are for example normal stress equal to zero, normal gradient of pressure equal to zero or pressure equal to zero have been adopted. In the present paper, a new approach for the open boundary condition of pressure Poisson equation has been proposed in which the pressure boundary values can be update for each time step by solving the boundary pressure Poisson equation which consists of the elements adjacent to the open boundary. The present approximation method is effective for the flow-through problems or the out-flow problems, like as wind engineering in architecture. In order to demonstrate the validity, the numerical results about back step flow and vortex shedding problem have been shown with R_e≦10^4.

The purpose of this paper is to report the fundamental data for natural ventilation caused by the ventilator which is equipped with building. In this paper we describe a wind tunnel invesitigation into the space static pressure surrounding tall model when low models are placed around of tall model in a simulated atmospheric boundary layer. Measurements are made of the influence of the height of low models and the distance of models. The results are presented in the form of coefficient of space static pressure, normalized by means of dynamic pressure of free stream. And they are compared with the space static pressure surrounding tall model in isolation.

Deposition of aerosol particles on semiconductor wafers is an important problem in manufacturing of integrated circuits. A model for predicting particle deposition in unidirectional flow cleanrooms is presented in this paper. Firstly, air velocity near a wafer surface was measured, and it was confirmed that the airflow in unidirectional flow cleanrooms is turbulent. Then the vicinity of a wall in turbulent flow is divided into turbulent zone, turbulent boundary layer, eddy diffusion sublayer and particle diffusion sublayer, and the eddy diffusivities in each zone are discussed. In the turbulent zone, the eddy diffusivity DT may be regarded as independent of the distance from the wall. Both the air velocity and the particle concentration have constant values. By Prandtl's theory, DT is proportional to the distance y from the wall in the turbulent boundary layer. The dominant machanism of particle transfer is turbulent diffusion. Within the eddy diffusion sublayer, the transfer of momentum is dominated by viscous forces, and the effect of weak turbulent fluctuations can be neglected. However, the situation is quite different for particle diffusion. Even weak fluctuations contribute significantly to particle transfer. DT is proportional to y3 in this sublayer. In the particle diffusion sublayer extremely close to the wall, the eddy fluctuations are so small that diffusion occurs principally by Brownian diffusion, i. E., within this sublayer, DT is much less than Brownian diffusivity D. According to the above-mentioned diffusivities, a model for predicting particle deposition in turbulence is proposed, including the effects of electrostatics and sedimentation. It is concluded as follows: 1) The fluctuation velocities near the wafer surface are about 10-15 % of time-averaged air velocities. 2) The deposition velocity obtained by the present model is about 10 times greater than that of the model in laminar flow for small uncharged particles. 3) The theoretical calculations by the present model agree well with experimental data.

In this paper, are disscussed the effect of the thermal mass on the seasonal energy consumption of auxilixry heating in direct gain system through the experiments of two heating seasons using four test cells which have different thermal mass. The results are summarized as follows; 1. The seasonal energy consumptions of the test cells which have thermal mass were 25 % to 29 % less than that of no thermal mass test cell. 2. The effect of the thermal mass on the energy consumption of the test cells varies with the differnces of solar gain in the heating season. Therefore, in the case of disscussing the seasonal energy consumption of massive building, it is required to investigate covering all the period of the heating season. 3. The average of diurnal energy consumption of auxiliary heating in the heating season can be estimated by the average of the diurnal solar gain in the heating season. 4. The actual thermal capacity of massive test cell, which was calculated using the swing of room air temperature in the interrupted period of heating from 10 pm to 5 am, is closely related to the diurnal solar gain and the diurnal energy consumption.

A computer simulation model for the freezing and melting processes of an ice storage system has been developed to estimate the seasonal energy consumption of air conditioning systems with ice storage tanks. The values of the parameters for the model were obtained through a series of experiments conducted on test equipment. The results of the simulation were compared with experimental results to determine the adequacy of the simulation. As a result it was revealed that the model was of practical use not only in cases of constant water flow rate and constant input water temperature, but also of variable flow rate and variable temperature.

The purpose of this article is to clarify the system of making teams in design organizations. In a sense design work is a connection in many different staffs. So, there are problems of human factor. The results of this study are as follows; 1) Typology of design teams: Design teams are classified into 10 types from five aspects. Each type of design team has a different purpose and characteristic features. Such as, combined or separated in equipment and structure planning staffs, specialized or generalized in building use, project oriented or team oriented, continuous or partial in design process, independent or subordinate in decision-making. 2) Characteristics of organization structure I Designers organizations are characterized from three aspects, composition of departments, a team unit size in a design organizations and control system of design process and decision making. 3) Design team types and organization structure: A type of design team is determined by the combination of these characteristics of organization structure.

La Chapelle de Ronchamp est loin d'etre l'architecture de 5 points que Le Corbusier a declare. Elle n'a ni pilotis, ni toit-jardin, ni fengtre en longuer. Quelle place cette oeuvre occupe-t-elle chez Le Corbusier ? A propos de Ronchamp Le Corbusier dit "Contact avec un site, situation dans un lieu, eloquence du lieu, parole adressee au lieu, Aux quatre horizons". D'apres lui, cette chapelle n'est pas un fanion <baroque>, mais un phenomene acoustique introduit dans les domaines des formes". D'ailleurs, collaborant avec Savina, il fait les sculptures expliquees comme plastique acoustique. De me"me qu'il existe un mgme notion artistique entre 1'architecture et le sculpture. II nous est done possible de dire que Ronchamp ne signifie pas un changement de son esprit pour l'ar-chitecture, mais un maximum de ses oeuvres. Car, ces sculptures expriment le developpement de ses oeuvres d'art. D'apres lui, cet edifice est ne. du paysage de l'alentour. II y parle de "l'espace indicible", qui constitue, pour ainsi dire, l'espace ideal dans les oeuvres architecturaux de Le Corbusier. Ainsi, on peut reconnait, a Ronchamp, la manifestation du monde architectural qui lui est propre, developpee bel et bien par le canal des oeuvres d'art et d'architecture chez Le Corbusier.

This paper is one of works in which I intend to clarify the castle town's planning methods of Japan. The summary in this paper is as follows: The water works in castle towns were recognized as an important town facilities. The water works conducted in the non-covered ducts were constructed and served in the the end of sixteenth century both as livings only in the zone of the Samurai-class and defence lines of castle towns. This tendency of the precedence for the zone of the Samurai-class were succeeded in after ages. However water works by open grooves were extended to the zone of the artisans tradesmen in the seventeenth century. The simultaneous constraction in both zone depends on each reason such as a compeled moving of their zone to the place where people could get only bad quality water, the appearance of influential towns men and etc.
