School of Engineering and Applied Science School of Engineering and Applied Science (SEAS) Department of Mechanical & Aerospace Engineering

Computational Aero and Hydrodynamics Laboratory (CAHL)


CAHL is a Computational Fluid Dynamics (CFD) lab directed by Dr Chunlei Charles Liang. It was established in the MAE department of GW on August 1st, 2010.

In CAHL, we develop numerical solvers for both incompressible and compressible flows and we model interdisciplinary problems related to Aerospace, Mechanical, Civil, Marine, Chemical, and Biomedical engineering as well as Astrophysics.
