They work like a vacuum pump but without usage of any moving part and therefore they can save energy. They are devices that use the energy of a high pressure fluid to move a low pressure fluid and enable it to be compressed to a higher pressure according to the principle of energy conversion. Thermocompressors are widely used in a large number of industries that use steam as their heating medium or as a power generating utility. This device uses water vapor as the working fluid and operates at 7.5 bar motive pressure, 63☌ and 80☌ for suction and discharge temperatures, respectively. The results indicate that these variables can affect both the entrainment ratio and critical back pressure. Finally, the effect of various nozzle exit plane diameters which cause different Mach numbers at the nozzle exit is investigated on the thermocompressor performance. Then its performance is analyzed by choosing different operating conditions at the boundaries and also different area ratios which is one of the significant geometrical factors to describe the thermocompressor performance.
Since the flow is turbulent and supersonic, CFD is an efficient tool to reveal the phenomena and mixing process at different part of the thermocompressor which are not simply obtained through an experimental work. This paper first describes the flow behavior within a designed model of a thermocompressor using the computational fluid dynamics code, FLUENT.
The performance of a thermocompressor highly depends on its geometry and operating conditions. They work like a vacuum pump but without usage of any moving part and so they can save energy. Jet Flow combination type vacuum systems major applications in distillation, evacuation, drying, evaporation, cooling ete.Thermocompressors are widely used in a large number of industries that use steam as their heating medium or as a power generating utility. They are versatile in handling both wet and dry loads, can be supplied with low level skid mounted packages with instrumentation and withĬlosed loop seal water re-cycle system for vacuum pumps for the total reduction of effluent. Jet Flow combination type vacuum systems provide a solution for high vacuum operations. Jet Flow Hybrid Ejector systems areĭesigned to operate at the same capacities and suction pressures as conventional steam jet ejector systems. It can be configured as single or multi-stage ejectors, single or two-stage liquid ring vacuum pumps and inter-condenser. This type of combination system can achieve vacuum as high as 0.05 Torr. A typical combination of steam jet ejector system followed by inter-condenser and liquid Jet Flow Steam Jet Ejector and Liquid Ring Pump Combination type Hybrid Vacuum Systems are getting popular in major Chemical, Soap, Food, Edible oil sectors.
