Simulation and Experimental Validation of Direct Heating of Dhruva Fuel Rod for β Heat Treatment
β heat treatment of Uranium rods is carried out for randomization of oriented grains (called texture) developed during hot rolling or hot extrusion operation. During this process, Uranium rods undergo heating of up to 740 Deg C followed by water quenching. The objective of this work is ... Mehr lesen
Finite Element Analysis of Transient Ballistic-Diffusive Heat Transfer in Two-Dimensional Structures
For the last two centuries, the conventional Fourier heat conduction equation has been used for modeling a diffusive nature of macroscale heat conduction by considering the energy conservation and Fourier's linear approximation of heat flux. However, it cannot accurately predict heat ... Mehr lesen
Multiphysics Modeling of a Grain Storage Chamber
Proper storage of grains depends on minimizing attacks of insects, fungi, mites, etc. Development of such pests can be controlled by controlling the temperature of the storage chamber. Hence, before designing grain storage chambers, mathematical modeling and numerical simulations should ... Mehr lesen
Implementation of a Viscoelastic Material Model to Simulate Relaxation in Glass Transition
Introduction: Glass relaxation occurs in a range of temperature during transition from equilibrium to super-cooled liquid. Viscoelastic material model can be applied to simulate glass behavior during the glass transition regime and to predict the glass deformation and stress evolution. ... Mehr lesen
