Biography

Xingjun Fang is interested at developing fundamental understandings of complex turbulent flows stemmed from realistic multi-physics applications. He was a research associate in the Turbulence and Hydraulic Engineering Laboratory (THEL) under the supervision of Prof. Mark Tachie at the University of Manitoba. He is conducting cutting-edge researches on turbulent separations induced by surface-mounted bluff bodies using state-of-the-art PIV systems, including the time-resolved particle tracking with shake-the-box technique. Other than his expertise on the experimental fluid dynamics, he also has profound understandings and extensive experience on computational fluid dynamics. He has developed/modified multiple parallel computing codes using both Fortran and C/C++ program languages implementing a wide range of numerical algorithms, including the finite-volume, finite-difference, spectral-element and pseudo-spectral methods. He has extensive experience conducting direct numerical simulation (DNS) and large-eddy simulation (LES). His expertise also extends to novel concepts of turbulence modelling approaches.
To analyze the numerical and/or experimental results, he has developed a variety of post-processing codes using the Matlab, Fortran or C/C++ languages to implement advanced statistical analyses of turbulence theory, such as energy spectrum, linear stochastic estimation, proper orthogonal decomposition, dynamic mode decomposition, various interface detection techniques and vortex detection techniques. These analysis techniques have been extensively used to study a broad range of turbulence problems, including isotropic turbulence, turbulent flows and heat transfer in a rotating square duct, turbulent flows over different shaped surface-mounted riblets, as well as separated and reattached turbulent flows over bluff bodies.
