Professor Professor Collins' research focus is on the application of direct numerical simulation to the study of a broad range of turbulent processes. Specific areas of interest include:
(i) turbulent transport of aerosol particles and droplets;
(ii) mixing and chemical reaction in turbulent flows;
(iii) materials synthesis in plasma devices;
(iv) turbulence-induced redblood cell damage in prosthetic devices. A unifying theme of this work is the importance of fine scale (micro-turbulence) transport to these phenomena. A second focus of his work is the development of a new class of turbulence models that is capable of describing micro-turbulence
processes. Recent contributions have been made toward extending fundamental spectral theories of turbulence to these applications (i and ii). Current emphasis is on validating the models and incorporating them into CFD codes.
