Abstract: In thermal power stations cooling Cooling Tower plays vital role. Along with stresses due to wind load, Seismic load, thermal stresses are predominant in tower. Using ANSYS we can check its thermal response which will be function of time. Natural Draught hyperbolic cooling towers are characterizing land marks of power stations. They comprise of a thin concrete shell of revolution are common place in civil engineering infrastructure. The wind load is always the dominant load in the design of the cooling tower due to its large size, complex geometry and thin wall. This paper deals with the study of thermal analysis of two existing cooling towers of 143.50m and 172m high above ground level with varying thickness in accordance with IS 11504. These cooling towers have been analyzed for thermal loads using ANSYS software by assuming fixity at the shell base. The analysis of two existing cooling towers has been carried out using 8 noded SHELL 181 element with uniform SHELL thicknesses.
