Professor Kleinstreuer’s long-term goal is to provide students with a high-quality education in engineering and to perform cutting-edge research that responds to national needs in science and technology.

He recently developed the graduate-level course entitled “Modern Topics in Fluid Dynamics” (MAE 589K). This course treats such modern topics as microfluidics, bio-fluids, and nanofluid flow. At the undergraduate level, he teaches Engineering Thermodynamics I (MAE 301) as well as Fluid Mechanics (MAE 308). Although these are courses that follow a classical coverage of material, he also presents energy transfer and fluid-particle flow animations to help students visualize the different phenomena being treated. Furthermore, Student White-Board Performance (SW-BP) is an integral feature of advanced learning.

As a faculty advisor, Dr. Kleinstreuer guides his students to meet industrial and academic challenges. His students have a strong knowledge base in physics, applied mathematics, and gain a strong foundation in computer modeling of complex multi-physics phenomena.

Outside of work, Dr. Kleinstreuer enjoys family activities such as tennis, chess, sailing, and the arts.

Research Description

Dr. Kleinstreuer is interested in computational biofluid mechanics, convection heat and mass transfer, and system optimization. He is presently studying computationally: 1) fluid-particle dynamics in the human respiratory system, including optimal targeting of inhaled drug aerosols; 2) radioactive micro-sphere transport in the hepatic system to reduce/eliminate liver tumors; 3) fluid-structure interaction in stented aneurysms, associated with rupture prediction and novel stent-graft design; and 4) nanofluid flow in micro-channels applied to cooling devices and bio-MEMS.
