Dr. Straatmanís research is directed mainly at the development of new capabilities in Computational Fluid Dynamics (CFD) and at convective heat transfer. Areas of focus in CFD include the development of phenomenological models and the prediction of non-stationary turbulent flows using VLES. Convective heat transfer research is directed at the characterization of porous metals for convective enhancement and the development of compact heat transfer devices.
Dr. Straatman conducts fundamental research aimed at the development of models and algorithms that extend the capability for accurate simulation of fluid and heat flow. Of particular recent interest has been the development of accurate discretization techniques for conjugate heat/fluid flow modeling in fluid/porous/solid domains. Robust models have been developed to deal with transitions between fluid/porous regions and porous/solid regions. These interface formulations have extended the capability of our conjugate codes to deal with high Reynolds number flows with and without energy transfer and contact resistance. Of particular significance is his recent development on the modeling of thermal dispersion in high-conductivity porous media.
Additional research is directed towards the prediction of non-stationary turbulent flows using Very Large Eddy Simulation (VLES) techniques. Applications of interest include airflow around bluff bodies with and without heat transfer, wind-induced flows in closed shallow lakes, and solid-vapor multiphase flows in fluidized beds and nozzles. Recent studies on vortex shedding across a slender cylinder in proximity to a solid wall have provided new insight on the suppression of vortex shedding.
Current research on porous metals for convective enhancement includes a combination of laboratory experiments, engineering modeling and CFD. Experiments have been conducted to characterize the permeability and void-level heat transfer of various graphitized carbon foams. Engineering models have been developed to describe the internal structure of the porous material and the hydrodynamic and thermal performance of porous graphitic foam devices. Continued effort is directed at modification of the foam structure to optimize the balance of hydrodynamic and thermal performance of the carbon foam, and at multiphase convective heat transfer.
