A dynamic 2D axisymmetric CFD model, coupled to a 1D bed model, has been developed to simulate the production of lime in a rotary kiln. The model simulates heat transfer caused by radiation, convection and conduction between the gas, wall, and bed to determine the axial bed temperature in the...

The current study investigates the interaction of a piezoelectric dislocation with a multi-layered coated fiber inhomogeneity embedded in an infinite piezoelectric solid. In our study, three dissimilar material phases are involved: the matrix, the inclusion and the multi-layered coating layers....

We study the evolution of chaotic mixing in an initially stratified circular vessel. The bottom and top halves of the vessel are filled with viscoplastic and Newtonian fluids. A circular stirrer in the vessel promotes the mixing. We considered three different viscosity ratios to understand the...

Abstract—Spark Assisted Chemical Engraving (SACE) is a non-traditional micro-machining technology, with one of its unique characteristics being the physical distance relationship between the tool and workpiece during machining. Previous papers have illustrated that maintaining space between the...

Fatigue-induced crack initiation and growth are common in cyclically loaded structures. Crack reduces the structures' strength and increases the risk of failure. Engineers have been using degradation models like Paris' law to relate crack length to the magnitude of the applied load to schedule...
