UHAERO is a project conducted by the Department of Mathematics at the University of Houston dedicated to the modeling and simulation of atmospheric aerosols.
Our focus in this project is primarily on predicting aerosol phase behavior because of its important effects on the physical, chemical, and optical properties of the atmospheric particles. So far, the intended research is in the area of mathematical modeling and computation of phase equilibria and phase transitions in atmospheric particles containing both inorganic and organic compounds.
