Experimental and Numerical Studies on Water Cooling Tower Performance
Volume 25, Issue 4 , June 2007, Page 512-533
Abstract
Theoretical and experimental studies were conducted on forced draftwater cooling tower. In such towers, the heat and mass transfer take placefrom the hot water to the bulk air, which ... Read More ...Numerical Study of Flow InMechanically Ventilated Rooms Under Non- Isothermal Conditions
Volume 25, Issue 4 , June 2007, Page 534-542
Abstract
A computational procedure was conducted in (3x3x3 m) rooms and in a full–scale model building to study the effect of supply temperature on the roomflow patterns in mechanically ... Read More ...The Effect of Size and Location of a Heating Source on the Buoyant Flow in a Heated Space
