A computational model for short-range van der Waals interactions between beams and shells

We consider potential-based interactions between beams (or fibers) and shells (or membranes) using a coarse-grained approach with focus on van der Waals attraction and steric repulsion. The involved 6D integral over volumes of a beam and a shell is split into a 5D analytical pre-...

Numerical investigation of the effective heat transfer coefficient for red clay hollow bricks

This study presents a numerical investigation of the effective heat transfer coefficient in red clay hollow bricks, accounting for the combined effects of heat diffusion in the solid clay and natural convection and thermal radiation within the air-filled cavities. Heat conduction...
