Question 4
The company which you work for has developed a novel tubular reactor.
which has a bespoke (irregular) geometry to enhance internal mixing. You
have been asked to analyse the velocity and pressure profile within this
reactor.
(i) Describe ?x(without actually having to carry out any calculations) the
step by step procedure which you would use to carry out the above
task, demonstrating your knowledge of the Navier Stokes equations
and how these may be applied numerically to such irregular
geometries.
A 1.8m diameter tank of standard geometry is to be used as a fermentation
vessel. The vessel will contain liquid to a depth of 1.8m and the contents are
to be agitated using a 0.6m diameter disk turbine impeller with a rotational
speed of 3rps. Air is to be admitted to the liquid through a sparger located
beneath the impeller. It may be assumed that the liquid contains cells, cell
products, nutrients and electrolytes.
(ii) Estimate the maximum allowable air flowrate for the proposed system
(iii) For a working air flowrate equal to 30% of the value in (ii) above
calculate the expected gas holdup and the interfacial area.
(iv) Show that the effects of liquid composition are significant in this
application.
** Please note that the use or description of commercial software
packages/approaches is not considered a valid response to part (i). Please
demonstrate your engineering knowledge of how this may be achieved using
first principles.
