This paper describes an experiment and the analysis of the heat transport capacity of heat pipes with triangular and rectangular grooves. The upside wall of the retangular heat pipe was made of a grooved metal plate and the bottom wall was made of glass for visual inspection. The heat transfer performances of six types of rectangular groove and three types of triangular glooves were obtained by changing the heat pipe tilt and reversing the heat pipe upside down. A theoretical model has been developed to predict the performances. In this model, gravity effect accompanied with the liquid recession into the groove bottom was taken into consideration. The maximum heat transfer rate of the triangular grooved heat pipe varied with the orientation of the groove openings and theoretical results agreed well with the experimental data.

The relation between heat transfer characteristics of convex louvered fins and air flow patterns through fins is studied by heat transfer measurements and flow visualization techniques. It is found that (1) the convex louvered fins are effective to improve heat transfer performance and (2) the optimum value in slope angle of convex louvered fins exists.

A rotating condenser with a scraper is considered as a new method used in condensing heat transfer augmentation. In the previous papers, we analyzed the case where the condensate film on the vertical and the horizontal rotating cylinder was scraped off mechanically by the plate, and we clarified the condensate states and the enhancement due to scraping. In this paper, we report the experimental results for the condensation of R-11 corresponding to the above analyses. The distributions of cylinder surface temperature and the mean heat transfer coefficients are obtained. The effects of speed of rotation and temperature difference between vapor and condenser surface are made clear. The enhancement due to scraping is arranged in terms of the mean Nusselt number ratio and compared with analytical results.

Three-dimensional characteristics of natural convection around and isothermal, vertical flat plate of short height and narrow width were made clear by means of the three-dimensional numerical analysis. New transformation of coordinate system was introduced into the numerical analysis. From three-dimensional stream lines and distributions of the local Nusselt number obtained, it is found that three-dimensional behaviors are quite evident in the natural convective field with low Grashof number. Furthermore, the effect of the aspect ratio, viz. the width of plate, on heat transfer rate is qualitatively good agreement with the former experimental result.

Effects of near ultraviolet radiation on the formation and the photolysis of methylnitrite formed by a reaction between unburned methanol and NO
x emitted from a methanol fueled S.I. engine were investigated. Sampled exhaust gases were introduced into a reactor tube with dilution air. Near ultraviolet rays, ranging from 310 to 400 nm, as an equivalent of sunlight, were irradiated to the sample gases at a normal temperature and pressure. Formation of methylnitrite was activated by the ultraviolet irradiation. Furthermore, photolysis of methylnitrite was observed at the same time. As a results of photochemical reaction, most of the methylnitrite formed from unburned methanol was converted to methylnitrate in all diluted sample gases.

In order to make clear the thermal structure of the atmosphere in urban area, one-dimensional numerical simulation is performed. Paticular attention is paid to the effects of condition of the earth surface, aerosol and artificial heat release. The results indicate that the temperature in urban area is generally higher than that in rural one and that the inversion layer near the earth surface in the urban area disappears at night in the winter season due to surface roughness and artificial heat.The considerable difference is formed in temperature in rural and urban areas for several hours before and after sunset. Aerosol has much effect in the daytime and the maximum effect of the diameter is found in the case when the diameter nearly equal to the wavelength of the visible light.

The laminar flow induced by suction at the center of circular vessel and the trajectory of a spherical particle settling freely in it are studied with a view to developing highly effective circular settling tank. Numerical solutions of vorticity transport equations showed the following results; there was a zone of recirculation along the side wall of the vessel, the flow characteristics rather depended on the depth of influent weir than Reynolds number. The numerical results were in agreement with the measurements obtained with the aid of dye-method. The trajectory of a particle in the vessel is simulated by using of the numerical results. The trajectory of a particle is similar to that of an ideal rectangular settling basin, but an increase in the initial distance between particle and the bottom of influent weir leads to a decrease in settlig time.
