Effect of Buckling Due to Wind Load on Analysis of Natural Draught Cooling Tower
This paper presents the study of buckling effect on natural draught cooling towers. Natural draft cooling tower(NDCT) is the describing milestones of intensity stations and are utilized as heat exchangers in Thermal power plants. Two cooling towers i.e. Cooling Tower 1 (100.0 m), Cooling Tower 2 (200.0 m) with variation in elevation and thickness of shell are considered for the analysis. Using ANSYS Software, which is a FEA-based, the Eigen value buckling analysis is carried out for two cooling towers. Natural draught cooling towers have been modelled considering top end to be free and bottom end to be fixed. The study has been done in detail about the finite shell element. Here three various cases have been considered for the study of the effect of buckling on analysis of the natural draught cooling tower. Case 1—Height is kept constant and thickness of shell is varied from 400 to 800 mm. Case 2—Height is varied and thickness of shell is kept constant. Case 3—Both height and cooling tower thickness of shell is varied. The behavioural changes of considered cooling towers are examined using ANSYS, with Variation of its height and thickness for initial 6 buckling modes. Maximum Deformation, Maximum Principal Stresses are obtained and compared.
