Counterfeit construction products from low-cost sourcing countries

Counterfeiting has been around since ancient times. Counterfeiting in modern times was once widespread and not confined to any geographic region. With the globalization efforts following World War II, counterfeiting became an international problem, much of it emanating from Japan’s developing manufacturing-based economy. As Japan’s economy...

A simple momentum forcing method on unstructured Cartesian mesh for immersed bodies in incompressiblle flows

The incompressible Navier-Stokes equations are solved by an implicit pressure correction method on unstructured Cartesian meshes. A simple immersed boundary method is developed to treat arbitrary solid bodies in the flow field. A direct momentum forcing term was added to cells inside the immersed body to enforce the no-slip boundary condition....
