Hollow self-inducing impellers: Flow visualization and CFD simulation

Assessment of standard k–ε, RSM and LES turbulence models in a baffled stirred vessel agitated by various impeller designs

“…All the computations have been performed using FLUENT 6.2. (2005), whose successful application has been documented in the literature (Bakker et al, 2001;Rocchi and Zasso, 2002;Roussinova et al, 2003;Hu and Kazimi, 2006;Wang et al, 2006;Murthy et al, 2007). The details of the turbulence modeling are discussed in Section 4.…”

Large Eddy Simulation for Dispersed Bubbly Flows: A Review

“…In the published literature, the knowledge of flow pattern has been employed for the estimation of equipment performance such as mixing (Joshi and Sharma [62], Joshi [63], Ranade and Joshi [64], Ranade et al [65], and Kumaresan and Joshi [66]), heat transfer (Joshi et al [67], Dhotre and Joshi [68]), Sparger design (Dhotre et al [69], Kulkarni et al [70]), gas induction (Joshi and Sharma [71], Murthy et al [72]), and solid suspension (Raghava Rao et al [73], Rewatkar et al [74], and Murthy et al [75]). Joshi and Ranade [76] have discussed the perspective of computational fluid dynamics (CFD) in designing process equipment with their views on expectations, current status, and path forward.…”

Hydrodynamics in the Blade Region of a Self-Aspirating Disk Impeller

“…This is due to the wide dissemination of these impellers in the industry. For self-aspirating impellers is much less information in literature (Murthy et al, 2007, Murthy et al, 2008. In our study by LDA method the profiles of average velocities and RMS were determined in planes: symmetrically between baffles and 2.5° behind baffle .…”
