During thermal processing, parts are usually subjected to continuous heating and cooling cycles during which microstructural and mechanical evolutions occur simultaneously at different length and time scales. Modeling of these processes necessitates dealing with inherent complexities such as large material property variations, complex couplings and domains, combined heat and mass transfer mechanisms, phase transformations, and complex boundary conditions. In this study, a finite element method based mathematical framework capable of predicting temperature history, evolution of phases and internal stresses during thermal processing of materials was developed. The model was integrated into the commercial FE software MSC.Marc® by user subroutines. The accuracy of the model was verified by simulating the quenching of hollow steel cylinders. Simulation results were compared with SEM observations and XRD residual stress measurements. According to the results, the model can effectively predict the trends in the distribution of microstructure and residual stresses with remarkable accuracy.

A FEM based framework for simulation of thermal treatments: Application to steel quenching Şimşir, Caner; Gür, Cemil Hakan (2008-12-01) During thermal treatments, materials are usually subjected to continuous heating and cooling cycles during which microstructural evolution and mechanical interactions occur simultaneously at different length and time scales. Modeling of these processes necessitates dealing with inherent complexities such as phase transformations, large material property variations, complex couplings and boundary conditions. In this study, a mathematical framework based on finite element method (FEM) capable of predicting te...
A Simulation of the Quenching Process for Predicting Temperature, Microstructure and Residual Stresses Simsir, Caner; Gür, Cemil Hakan (2010-02-01) A finite element model capable of predicting the temperature history, evolution of microstructure and residual stresses in the quenching process is presented. Proposed model was integrated into Msc. Marc software via user subroutines. Verification of the model was performed by X-ray diffraction residual stress measurements on a series of steel cylinders quenched. (C)2010 Journal of Mechanical Engineering. All rights reserved.
3D finite element simulation of steel quenching in order to determine the microstructure and residual stresses Şimşir, Caner; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2008) In the course of thermal treatments, materials are usually subjected to continuous heating and cooling cycles during which microstructural evolution and mechanical interactions occur simultaneously at different length and time scales. Modeling of these processes necessitates dealing with inherent complexities such as large material property variations, complex couplings and boundary conditions, coupled heat and mass transfer mechanisms and phase transformations. In this study, a mathematical framework based...
Analysis of single phase convective heat transfer in microchannels with variable thermal conductivity and variable viscosity Gözükara, Arif Cem; Güvenç Yazıcıoğlu, Almıla; Department of Mechanical Engineering (2010) In this study simultaneously developing single phase, laminar and incompressible flow in a micro gap between parallel plates is numerically analyzed by including the effect of variation in thermal conductivity and viscosity with temperature. Variable property solutions for continuity, momentum and energy equations are performed in a coupled manner, for air as a Newtonian fluid. In these analyses the rarefaction effect, which is important for the slip flow regime, is taken into account by imposing slip veloc...
EXPERIMENTAL ANALYSIS AND TRANSIENT SIMULATION OF HEAT TRANSFER INSIDE THE FINNED TUBE ADSORBENT BED OF A THERMAL WAVE CYCLE ÇAĞLAR, AHMET; Yamali, Cemil (Begell House, 2019-01-01) Heat transfer enhancement inside the adsorbent bed of a thermal wave adsorption cooling cycle is investigated both experimentally and theoretically. Various adsorbent materials are tested using a finned tube adsorbent bed for the thermal wave cycle. The mathematical model is well defined, including a 2-D coupled heat and mass transfer analysis. This study presents the effects of heat transfer fluid velocity, regeneration temperature, condenser pressure, and particle diameter on the heat transfer enhancement...
