Finite Element Analysis of Steam Turbine Components for Real Life Assessment Studies of 210 MW Steam Turbine
Abstract: The turbine rotor or steam turbine rotor is subjected to temperature variations in short periods of time due to the start and stop cycles of the turbine. This causes sudden changes in the temperature with transient thermal stresses being induced into the turbine rotor. The transient effect is due to the changes in the material properties like density, specific heat and Young’s modulus. The estimate of thermal stresses induced in …

FE Analysis and Experimental Validation of Residual Stresses in Arc Welding
Abstract: This paper presents finite element analysis (FEA) of residual stresses developed in arc welded butt joints. Residual stresses attributed to welding pose significant problems in the accurate fabrication of structures because these stresses heavily induce brittle fracturing and degrade the buckling strength of welded structures. Therefore, estimating the magnitude and distribution of welding residual stresses and characterizing the effects of certain welding conditions on the residual stresses are deemed necessary.Keywords: …

Quasi-Static Thermal Stress Analysis in a Thin Circular Cylinder Due To Internal Heat Generation Under Transient Temperature Conditions
Abstract: This paper is concerned with inverse quasi-static thermal stress analysis in a thin circular cylinder due to internal heat generation under transient temperature conditions. The internal heat generation is modeled as a cylindrical surface heat source located in the annular region along the axial length of the cylinder. This source is placed concentrically inside the cylinder and begins releasing heat spontaneously at a specific point in time. The thin circular …

Thermal Analysis of Casting using ANSYS: A Review
Abstract: The major requirement of any foundry is to provide the high quality casting products. Since the quality is depended upon thermal stress and solidification of the casting, a thermal analysis is a key area to work on. Heat transfer coefficient is the vital element of any thermal analysis. Mould and the casting interface is the most critical area that gets affected during the solidification. Heat transfer ratio at the inter …

Design and Thermal Analysis of Fins for Air Cooled Engine by Varying its Geometry
Abstract: An air-cooled motorcycle engine releases heat to the atmosphere through the mode of convection to facilitate this, fins are provided on the outer surface of the cylinder. The cooling fins allow the wind to move the heat away from the engine. The heat transfer rate depends upon the velocity of the vehicle, fin geometry and the ambient temperature. Low rate of heat transfer through fins is the main problem of …

Review of Subsea Pipeline for Minimizing Thermal and Pressure Expansion
Abstract: As the offshore oil and gas fields have been exploited in deeper water, subsea pipelines are required to operate at high temperatures and pressures. It causes subsea pipelines to be more subject to movements both in lateral and axial directions due to the loads produced by high temperatures and pressures. Some high temperature pipelines have experienced the cumulative axial displacement of an overall pipeline length over a number of start-up/shut-in …
