Numerical Study of the Effect of Vertical Wind Break on the Trough Collector's Drag Force

Wisam Ahmed Abd Al-wahid

The effect of the addition of wind break wall upstream the wind flow is studied numerically. The separation distance between the trough and wind break, and the wind break elevation as well as the wind flow velocity will be the variables of the present work. The computational work done by use a 5.0 COMSOL Multiphysics code to solve the problem. The results show a general decrease in the drag forces on the trough as well as the heat loss. The extreme values of separation distance and wall elevation causes an opposite defect results.
