Download or read book CFD Analysis of Flow Field in a Mixing Tank with and Without Baffles written by Carlos F. Rezende and published by . This book was released on 1996 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A computational technique has been developed to study the fluid motion in a baffled and unbaffled mixing tank. This technique was devised for a cylindrical mixing tank using a Computational Fluid Dynamics code, FIDAP. Two model analyses are presented in this thesis: Unbaffled tank steady state analysis. Baffled tank transient state analysis. The method presented in this thesis uses subroutines incorporated into the CFD program to impose the boundary conditions associated with each baffle in the tank. These boundary conditions are rebuilt for each time step to capture the effects of the relative motion between the baffles and the impeller. In addition, the use of parameters in defining the coordinates of the geometry, the density of the mesh, and the fluid properties allow a straightforward automation of the model. This automation considerably reduces the time to create a new tank geometry from scratch. Furthermore, the automation permits rapid model development to be used in selecting optimal tanks and radial impeller combinations."--Abstract.
