Abstract
AbstractIn the present study, simulation of a stirred tank using axial flow impeller has been studied numerically to see the behaviour of flow variables in the entire vessel. It is assumed that the flow is steady state, two dimensional, incompressible and axisymmetric. For simulation, Partially-Averaged Navier-Stokes (PANS) $$k_u-\epsilon _u$$

turbulence model has been taken into account. For discretization, control volume method along with upwind and power-law schemes have been taken. The solutions are obtained by using the SIMPLE algorithm. The boundary conditions for impeller are given by using the experimental data. The main objective is to investigate the influence of different filters width $$f_k$$

Abstract
![]()
Computational
fluid dynamics is a powerful method for scale-up
of reactors although it is still challenging to fully embrace hydrodynamics
and biological complexities. In this article, an aerobic fermentation
of Pichia pastoris cells is modeled in a batch OKTOP®9000
reactor. The 800 m3 industrial scale reactor is equipped
with a radial impeller, designed by Outotec Oy for gas dispersion
in the draft tube reactor. Measured Np of the impeller is used in hydrodynamics validation.
The resolved energy dissipation rate is compensated, and its influence
on mass transfer is analyzed and discussed. Gas–liquid drag
force is modified to simulate effects of liquid turbulence and bubble
swarms. Resolved steady state multiphase hydrodynamics is used to
simulate the fermentation process. Temporal evolution of species concentrations
is compared to experimental data measured in a small copy of the reactor
at lab scale (14 L). The effect of oxygenation on the P. pastoris cells cultivation is considered.
