1/2 which was established for the ligament-type disintegration on the disk can be applied approximately. But for the ligament-type disintegra tion of the fluid having high viscosity, due to the adhesive phenomenon of ligaments, effect of the sur face tension on the number of ligaments was reduced and that of radius of disk was increased. The number of ligaments was connected with volumetric flow rate. Adhesive inclination of ligaments was controlled by the numerical value of the dimensionless item ρ

Q is volumetric flow rate, γ

A mean particle size effective to the swarm of particles with size resented to apply the usual voidage function to the flow behaviour of them, when the particles are under steady homo-geneous flows in a continuous countercurrent extraction column. With this mean size, the observed rate of hindered settline of mixed size particles is well described by applying the slip velocity modulus. The properties of observed slip velocity modulus and particle diffusion are discussed and an approximate expression is developed for the voidage function of fluid bubbles. Finally, longitudinal dispersion of liquid droplets in continuous countercurrent extraction columns is formulated, showing moderate agreement with the observed data for R. D. C.

The dehydration of Isopropyl Alcohol over Silica-Alumina FCC catalyst (a pseudo-first order reaction) was done at atmospheric pressure, a carrier gas velocity below 40.0cm/sec, and in the temperature range between 200°C and 210°C in a slugging transport reactor. In this reaction study, close sized Silica-Alumina FCC catalyst of 200-250 mesh are used.
It was found that the results of the reaction fall into between those of piston flow and complete mixing.
The conversion calculated from Eq.(3) based on the “contact time model” for describing reaction results reached a conclusion that agreed well with the experimental reaction data.
Besides, a comparison of the reaction results in a slugging transport reactor and those in a transport reactor is presented.

The static and dynamic characteristics of a table feeder were studied. As the results, it was found that the static characteristics could be estimated with good accuracy if the shape of the powder bed was taken into consideration, and that the scraper should be inserted along the tangent of a concentric circle on the table to get a constant feed rate of high stability. On the other hand, experimental study on the step response of the table feeder following the step change in the position of the scraper revealed two types of responses according to the kind of powder materials, one was the derivative type and the other proportional. These responses were also analyzed.

According to the diffusion model, coefficients of axial mixing of particles in an inclined fluidized bed were measured experimentally. The following conclusions of discussion were obtained.
1) Mixing coefficients were correlated by Eq.(12) in this experimental condition.
2) Correlation of Eq.(13) was obtained on average inear velocity of particle,
us included in Eq.(12).

The experimental responses of dispersed phase that stayed on the liquid-liquid perforated plate column were obtained for step change in dispersed phase flow rate by using water (continuous phase)-kerosene (dispersed phase) system. The column consisted of three plates and each diameter was 8cm i. d. and plate spacing was 30cm long.
The deviations and the time constants of the top plate hold-up are larger than that for the other plates. The phenomenon of inverse response is found out in the top plate. The free area of the perforated plate and the pressure drop due to the outlet flow of continuous and dispersed phases influence upon the responses. Especially, the pressure drop due to outlet flow of continuous phase much influences the response patterns.

The use of a constant-temperature hot wire anemometer to measure droplet size is discussed.
Heat loss caused by a droplet hitting on hot wire is a function of droplet size. The electric pulse corresponded to droplet properties is overlapped on the heat compensation current which maintain hot wire temperature. The size analysis of pulses give the droplet size analysis of entrainment. The pulses were amplified, sorted by a discriminator circuit, and counted.
The results show that the hot wire method is effective to detect droplet in flow, and counting data show the droplet size distribution of liquid entrainment relatively.

In the ternary system acetone+methanol+water and its three associated binary systems: acetone+methanol, acetone+water and methanol+water, the vaporliquid equilibrium data at 760mm of Hg have been measured.
The liquid activity coefficients for the ternary system ware correlated with Nagata's modified Chao equation and with the Wilson equation, each of which gave satisfactory agreements.

Based on the previous fundamental investigations the new type heat exchangers with heat transfer surface of waving plates were designed. The press dies for waving plates could be easily manufactured. One type of them had the two dimensional flow channels partitioned with the progressive waves, and it showed, as expected, a larger heat transfer coefficient than the conventional one. The another type had the three dimensional flow channels formed by arranging the plates with the oblique wave patterns. This type is strong against the high pressure because the plates contact each other at many points of wave peaks of them. The most suitable configuration of the heat transfer plate was determined based on the results of the investigation on such factors as the distance of waves, and the oblique angle of the wave Pattern.
