Latest Patents

One of her latest patents is titled "Thermal flow simulation for casting/molding processes." This invention presents a numerical procedure for simulating the behavior of incompressible, viscous fluid during casting and molding. The method is grounded in classical fluid dynamic equations and employs control volume-finite element techniques to solve momentum and energy equations. It incorporates five additional modules that simulate fluid flow in the shot sleeve, heat transfer between the die and the heat transfer fluid, die cooling by lubricant, and the formation of mend lines. These enhancements provide realistic boundary conditions and improve the convergence of numerical solutions, leading to more accurate simulations of the die casting process.

Another notable patent is the "Equal order method for fluid flow simulation." This invention offers a method for solving the Navier-Stokes equation for viscous, incompressible laminar flows with moving free surfaces in complex domains. It utilizes fixed mesh control volume-finite element techniques to track fluid flow. By defining a Gauss point velocity vector as the average of its nodal counterpart, the method ensures that the velocity vector remains constant over the element. This approach eliminates common issues such as the checker-board problem and allows for precise evaluations of global mass conservation.
