This work presents a numerical model to study the effects of deposition and deposit erosion on solid moving object under prescribed motion. In this model, fluid flow, particle transport, erosion, conjugate heat transfer, movement are all considered simultaneously in fully coupled manner. The is modeled as first-order reaction, while shear-driven using threshold law. evolution front captured level-set method with two functions. capabilities demonstrated flat plate undergoing translational, rotational, combined motions, well four-blade rotor translational rotational motions. results indicate that higher typically occurs upstream facing surface due concentration region compared downstream region. With an imposed volumetric generation within object, layer acts insulating barrier, impairing transfer from flowing leading average temperature clean object. Furthermore, total volume increases Damkohler numbers critical shear stress, lower Erosion numbers. Consequently, rises increase volume.
