CFD and experimental studies of single phase axial dispersion coefficient in pulsed sieve plate column

CFD simulation and experiment of residence time distribution in short-contact cyclone reactors

“…Computational fluid dynamics tools are becoming powerful and popular to conduct reactor design and diagnosis, since they are less restricted by the operating conditions, less time-consuming and less costly [16,17]. In the literature, a simple and prevailing method to simulate the RTD is to model the tracer experiment by solving the species transport equation [18,19].…”

Implications of hydrodynamics on the design of pulsed sieve-plate extraction columns: A one-fluid multiphase CFD model using the volume of fluid method

“…Some resurgence in PSEC research is apparent over the past decade through new investigations into their hydrodynamics using computational fluid dynamics (CFD). However, these studies are mainly rudimentary, typically employing Reynoldsaveraged Navier-Stokes (RANS) methods using k-ε turbulence modelling to close the descriptive equations V C Mesh cell volume (m 3 ) (Yadav and Patwardhan, 2009;Kolhe et al, 2011;Sen et al, 2018). Whether this approach can be considered suitable for systems of such complexity is questionable.…”

Comparative study of dry pressure drop and flow behaviour of gas flow through sieve plate packing

“…[12,13] CFD technology has been widely used in researching the hydrodynamic process of the fluid in complex column interiors. [9,12,[14][15][16][17][18][19] It can not only provide a realistic picture of the internal flow field and critical hydrodynamic parameters for the design and performance analysis of the column, [12,14,20] but it can also enable changes in the geometric parameters of the interiors to be made using the single variable method and simulates the conditions where experiments cannot be conducted. [18] Tang et al [9] investigated the flow behaviour of single gas flow through a tridimensional rotational flow sieve tray using CFD simulation with the realizable k-ε turbulence model and verified the simulated results by comparing them with the experimental pressure drop and velocity results, respectively.…”
