Direct Numerical Simulations of Gas-Liquid Multiphase Flows

He is currently the Charles A. Miller, Jr. Distinguished Professor and Department Head, Department of Mechanical Engineering, Johns Hopkins University, Baltimore, MD, 21218 Peter V. Nielsen 1, Tryggvi Tryggvason2 1 Aalborg University, Aalborg, Denmark 20pus ehf, Akureyri, Iceland ABSTRACT An interconnection between a building energy performance simulation program and a Computational Fluid Dynamics program (CFD) for room air distribution will be introduced for improvement of tfie predictions We make heavy use of resources from our colleagues, in particular the excellent starter course of Prof Lorena Barba (12 Steps to Navier-Stokes), the public chapters from Prof Whye Teong Ang's excellent book on the boundary element method, and a great tutorial on finite volumes and multiphase flows by Prof Gretar Tryggvason. An Eulerian two-fluid computational fluid dynamics model has been developed for flows with microbubble drag reduction (MBDR). This paper focuses on recent validation studies for MBDR flows across a spectrum of Reynolds numbers. Direct numerical simulations and two sets of experimental flat plate boundary layer measurements are studied. Although many books have been written on computational fluid dynamics (CFD) and many written on combustion, most contain very limited coverage of the combination of CFD and industrial combustion.

The assumption of the sharp-interface is not always appropriate (Anderson et al., 1998) as the thickness of the interface may not be negligible comparing to the relevant scales especially near the critical temperature. Anderson et al. (1998) present a review of the models and Tryggvason 1988 used Lagrangian-Eulerian vortex methods for simulating the dynamics of perturbation in two fluid model. Zhang 1991 conducted numerical investigation to study the motion of spikes in RT interfaces by applying front tracking method on 2D Euler equations. Talat et al.2018 introduced the diffuse approximated method(DAM) Computational Fluid Dynamics I Short History of CFD Computational Fluid Dynamics I Numerical Approximations Computing pi, Gauss, etc.
