An analytical model for evaporative cooling
نویسندگان
چکیده
We have developed an analytical model for evaporative cooling [1]. By simulating evaporation as a sequence of discrete steps, we could predict the time dependence of all important parameters such as temperature, density, elastic collision rate. By incorporating trap loss due to background gas collisions into our model we derived the threshold conditions for “run-away” evaporation. This is characterized by an increase in the rate at which the cloud rethermalizes and ensures efficient evaporative cooling.

Effect of Using Evaporative Condenser Instead of Air Condenser in Window-air Conditioners
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 pre...

متن کاملTowards an Analytical Model for Film Cooling Prediction using Integral Turbulent Boundary layer
The objective of this work is to develop deep theoretical methods that are based on the solution of the integral boundary layer equations for investigating film cooling in liquid rocket engine. The integral model assumes that heat is transferred from hot free stream gas to the liquid film both by convection and radiation. The mass is transferred to the free srteam gas by the well-known blowing ...
