Development of a Moving Finite Element-Based Inverse Heat Conduction Method for Determination of Moving Surface Temperature
A moving finite element-based inverse method for determining the temperature on a moving surface is developed. The moving mesh is generated employing the transfinite mapping technique. The proposed algorithms are used in the estimation of surface temperature on a moving boundary with high velocity in the burning process of a homogenous low thermal diffusivity solid fuel. The measurements obtain...

متن کاملThe meshless local Petrov-Galerkin method for the analysis of heat conduction due to a moving heat source, in welding
Recently, the efficiency of computer modeling and simulations has been improving dramatically. Consequently, the structural analysis of welding phenomena based on thermaleelasticeplastic finite element method (FEM) can be performedwith a good accuracy in a short time. However, if themodel to be analyzed is large and it has a complex shape, problemsmight occur with preprocessing, such as themesh...
متن کاملTransient Three-Dimensional Thermal Analysis of a Slab with internal heat generation and heated by a Point Moving Heat Source
In this work, analysis of transient three-dimensional heat transfer in a slab with internal heat generation and heated by a point moving heat source along its axis is carried out using integral transforms methods. The heat input into slab or workpiece by the moving heat source is considered in the model. From the results, it was established that the temperature of the material during the heat t...
