fluid flow

Expert has been actively involved with the development of thermal-based therapies to enhance human health and also with the development of devices to deliver these therapies. His activities have encompassed human thermo-regulation in general, hyperthermia, hypothermia, prevention and control of wounds caused by elevated pressures or temperatures, protocols for enhancement of wound healing, animal models, mathematical models of human and animal thermoregulation, non-invasive and invasive thermally-related instrumentation, diseases and disabilities related to impaired blood flow, among others. His experience also includes designing devices to create the needed microclimates and macroclimates to promote wound healing.

biological heat transfer

Expert has broad experience in the development of models of complex heat transfer processes. These models encompass analysis, numerical simulation, and experimental simulation. He specializes in problems where the needed information for modeling is not fully available, and has developed a method for identifying and separating the knowledge that is strictly necessary from that of lesser importance. He also strongly advocates the use of available software whenever possible.

heat transfer modeling


thermal transient

Expert has designed convective and/or radiant chambers and tunnels for processing polymers, pharmaceuticals, cosmetics, and food products. He has also worked with the design of furnace-like chambers for the heat treatment of metals.
