Key words and phrases: braking heating; expansion cooling; gas-hydrodynamic calculation; squares of pressure equation; thermal separation; viscous dissipation; vortex effect; vortex tube.
Abstract: We show the contradictory interpretations of the mechanism of the vortex temperature separation effect and no basis for its scientific-physical calculation. An engineering gas-hydrodynamic method of calculation based on the determination of the hydrodynamic resistance of the vortex tube and its components has been proposed and further developed. The equation for calculating the squares of pressure difference, taking into account logarithmic expansion of a compressible medium, has been obtained. Subsequent thermal calculation is performed on the basis of clearly identified effects of braking heating, expansion cooling and viscous dissipation, with the introduction of the “reality” correction factors. An experimental apparatus has been designed and constructed; the results of extensive experiments with seven modifications to the vortex tube and a method of statistical analysis have been presented. The final equations have been specified by the experiments for the specific types of vortex tubes.

Key words and phrases: cracking ratio; drum; drying uniformity; microwave; rotary temperature distribution.
Abstract: The influence of microwave power, temperature and velocity of the hot air stream on drying rate, uniformity of drying and temperature of the material in microwave and microwave-convective drying of soybeans in the rotating drum was studied experimentally. Temperature of the material surface and drying uniformity were visualized and analyzed with the IR Thermal Imager. Compared with the sole micro-wave drying it was found that in the accelerating drying rate stage blowing hot air through the cascading bed of MW-heated soybeans is highly beneficial to reduce the material surface temperature, enhance drying rate and improve drying uniformity. How-everHowever, in the falling drying rate stage the effect of hot air on drying rate was not so advantageous since the drying uniformity was worsened and the material temperature increased with hot air temperature. On the other hand, higher hot air velocity increases drying uniformity and reduces material temperature in the falling rate period which dominates the drying process but worsens the quality of soybeans quantified in terms of the cracking ratio.
