Research Areas

Professor Alexeenko’s research has both theoretical and computational components and is centered upon development and application of new models and algorithms to study rarefied gas flow phenomena occurring in both high-altitude flight, such as spacecraft contamination, plume interactions, high-altitude aerothermodynamics; and in emerging technologies such as micro-electro-mechanical systems for space communications and micropropulsion and in vacuum manufacturing processes. Broadening applications of rarefied gas dynamics is one of her long-term research goals. Alexeenko's group at Purdue has developed fast computational algorithms and solvers for the deterministic, as opposed to the stochastic DSMC, solution of rarefied flow problems. Such new techniques are especially useful in studying low-speed and/or unsteady flows and have allowed to address several challenging problems, such as the aerodynamic damping in MEMS and shock wave propagation at microscale.
