Problems in condensers have led to significant reduction in availability and loss of production in power industry. Therefore, there is a need for improved condenser design, which, in turn, requires more comprehensive understanding of the fluid flow and heat transfer in condensers. With the development in computational techniques, numerical methods have proven to be useful in condenser analysis and designs. This study involves assessment and development of suitable turbulence models and closure relationships for condensation, interphase friction forces, non-condensable air and flow resistance of tube bundles. These steps play a key role in improving the simulation accuracy since most existing turbulence models and closure correlations were developed based on single-phase flows or flows in simplified geometries. The numerical results are compared with the experimental data to assess the performance of the proposed models.
Dr. Chao Zhang is a professor and former Director of Professional Programs of the Department of Mechanical and Materials Engineering at Western University. She is the fellow of the Canadian Society of Mechanical Engineering (CSME).
She received her Ph.D. in Mechanical Engineering from University of New Brunswick in 1990 and joined University of Windsor as a faculty member in the same year. She took up her present position in 1999.
Dr. Zhang is well known in the area of computational fluid dynamics and has contributed significantly in this field by developing numerical models and algorithms for the simulations of turbulent multiphase and reactive flows. The main field of her research is two-phase flows in condensers, turbulent reactive flows in industrial furnaces and automobile engines, and gas-solid and liquid-solid flows in fluidized beds, and supercritical fluid flow and heat transfer in nuclear reactors. She has published more than 200 technical papers.
