1D3D and 2D2D cyclones were tested at Amarillo, Texas, to evaluate the effect of air density on cyclone performance. Both airflow rate and cyclone inlet velocity change with the change in air density. Two sets of inlet design velocities determined by the different air densities were used for the tests: one set based on the actual airflow, and the other set based on standard airflow. Experimenta...

In this paper, the application of evaporative cooling for refrigeration cycle to reduce power consumption in hot climates is emphasized. Experimental and analytical investigations were performed in order to specify the effect of evaporative cooling condenser instead of the commonly used air cooling condenser in window-air-conditioners. Evaporative condenser can reject more heat, thereby preve...

The fuel efficiency of cooling air at the inlet marine low speed diesel engine with water-fuel emulsion combustion by ejector chiller utilizing heat exhaust gas along route line Mariupol– Amsterdam–Mariupol was estimated. values available refrigeration capacity chiller, intake temperature drop and corresponding decrease in specific consumption main varying climatic conditions were evaluated. Th...

During periods of heavy work, such as those expected in extravehicular activity, metabolic heat can be removed at nearly any reasonable rate with water cooled clothing. We have studied the cooling needed for various work levels up to 15 kcal/min (3600 Btu/hr), using five different programs of activity over 3 to 6-hour periods. With thermally isolated subjects, and using a fixed water flow rate ...

Effects that two different compound-angle film-hole configurations have on film cooling effectiveness are investigated. Effectiveness measurements have been made downstream of a single row of compound-angle cylindrical holes with a diameter of 7.5 mm, and a single row of compound-angle, diffuser-shaped holes with an inlet diameter of 7.5 mm. Both geometries were inclined with respect to the cov...

Formation temperature is an important parameter in geothermal drilling since it affects drilling fluid, operations and equipment, through mud temperatures. In this study formation temperatures of the five geothermal wells in Germencik-Omerbeyli field were estimated by using mud inlet and outlet temperatures obtained during drilling. GTEMP wellbore thermal simulation model was used to estimate t...

The three years since the introduction of 'gastric freezing' by Wangensteen and his associates (Wangensteen, Peter, Nicoloff, Walder, Sosin, and Bernstein, 1962a; Wangensteen, Peter, Bernstein, Walder, Sosin, and Madsen, 1962b; Peter, Bernstein, Sosin, Madsen, Walder, and Wangensteen, 1962) have witnessed a mounting scepticism as regards its safety and efficacy (Mcllrath, Hallenbeck, Allen, Man...

Blade cooling is a relevant topic in the design of modern gas turbine engines, because of the increase in performance due to the resulting increase in the inlet turbine temperature is counteracted by a corresponding decrease due to the air extraction from the high-p compressor. In this paper, a previous model published by De Paepe & Dick is revisited and extended: while the original model consi...

Heat pipe is a device that transports heat with minimal temperature drop using the latent heat of fluid in a closed container. In vertical type named as thermosyphon (Wickless), capillary action is replaced by the gravitational force, this condenser is placed above evaporator. In this paper, to investigate the effect of inlet air temperature and the air mass flow rate was studied. The temperatu...

A promising type of green transport, lithium battery-powered electric cars (EVs) have attracted a lot attention and interest in the current years. In this study, thermoelectric cooling with forced convection was designed possible method for thermal control battery system. Compared to free cooling, air TEC appear is leading work. Conditional tests are done on created system EV automobile vehicle...
