This study is about comparison of thermal and flow characteristics on the wind & radiant heat shield with STS mesh type screen for offshore plant. Numerical analysis was conducted to find transmission coefficient in the mesh and then analyse the flow characteristics about wind & radiant heat shield. The experiment method of solar radiation has been used as thermal radiation source to get the performance of radiant heat shield measurement. The sensor radiation device has been used to measure the reduction of solar radiation with various size of cells and at a distance of 0.5m and 1m from the cold face of the wind & radiant heat shield. The present study show reduction in radiation heat flux as various distance from the cold face of the radiant heat shield. Experimental results are presented for different type of mesh and distance of measurement.
