Professor Pollard's research interests are in computational and experimental fluid dynamics with particular interest in turbulence. His research seeks to uncover the physics of turbulence and attendant physical transport processes. Early work included modelling (Reynolds and Favre averaged) of processes that have in the past included combustion and radiation. Current work includes simulation (Direct and Large Eddy Simulation) of free round jets, incipient separation, flow in spacer filled channels, channel flows subject compressibility and pressure gradients and flow in the human airway and heart. His group has used Discontinuous Galerkin methods, Lattice Boltzmann methods and finite volume methods for their simulations. Analysis of data obtained from either DNS, LES or experiments is done using a variety of turbulence structure identification methods. Passive and active control of turbulence is used to enhance physical understanding. Experimental facilities include stereo PIV and hot wire, a 3m long flying hot wire facility, a wall jet facility and a closed loop bio-fluid facility.
Professor Pollard's additional research is the introduction of low carbon fuels into industries that have traditionally relied on fossil fuels. This includes the electricity generation, cement and other sectors. This work includes solar PV, biomass and wind.
Professor Pollard was a founding member, former Associate Director and Director of the Centre for Advanced Gas Combustion Technology of Queen's University. He was a founding member and inaugural president of the CFD Society of Canada (http://www.cfdsc.ca). He was a founding member and the Principal Investigator of the High Performance Computing Virtual Laboratory, HPCVL, (http://www.hpcvl.org/) as well as a founding member, Chair of the Board of Directors and President of C3.ca Association Inc. (http://www.c3.ca). Compute/Calcul Canada (computecanada.org) builds on the success of C3.ca. He was the innaugural Director of the Collaborative Master's Programme in Computational Science and Engineering as well as the innaugural director of the Sustainable Bio-economy Centre.
