Finite element method (FEM) was used for planar ablation problem of heat protection materials based on thermal analysis. ANSYS, a commercial FEM code, was employed for modeling and calculating, and material deleting and boundary moving problems were solved with its advanced techniques. Various heat flux (HF) densities ranging from 1 to 10 MW/m2 as thermal loads were investigated to the effects of heat conduction and ablation, respectively. The results showed that a sudden thermal load can cause great temperature rise and high thermal gradient near the surface of the material. The ablative quantity and ablation rate were also calculated, and mathematical models have been deduced for them.

Element Method

Thermal analysis of different types of the connecting rods are under stead state condition using finite element method. The energy equation and heat transfer equation in the solids are completely addressed and solved using the Newton-Raphson technique and finite element method. SOLID WORKS is used for modelling different types of connecting rods and ANSYS© software is used to perform this numerical investigation. Three different materials like structural steel, aluminium alloy and titanium are selected as the material of connecting rod to do the comparative studies. In a steady thermal analysis, properties like temperature distribution, total heat flux and directional heat flux are calculated. The knowledge of the above properties is required to identify the viscosity of oil used for lubrication and also temperature distribution is helpful to find the thermal deformation in the connecting rod. Temperature and convection co-efficient are the boundary conditions. 22°C is the initial temperature value and the value of convection co-efficient is 350W/m2°C. As a result of thermal analysis, titanium alloy is the best material among the three materials as it with stand higher temperatures, high lifecycle and high performance.
