The Prediction of Impingement Heat Transfer for Turbulent 2-Dimensional Slot-Jets.
Supervisors Prof H Iacovides and Dr T J Craft
Impingement cooling is a very efficient way of removing thermal energy
from a heated surface. Turbulent impingement is also difficult to compute
accurately, because of the complex character of the near-wall flow and
the presence of a stagnation point. Earlier research activity within the
group mainly focussed on axi-symmetric two-dimensional jets. The objective
here is to extend the work of the group to plane, slot-jets. A number
of cases for which experimental data are available will be computed with
different turbulence models and the resulting predictions will be compared
with the experimental data. An in-house CFD code, written in fortran,
for turbulent two-dimensional flows, will be used.
The Computation of Turbulent Buoyancy-Affected Flows Relevant to Nuclear Reactor Cooling Applications.
Supervisors Prof H Iacovides and Dr T J Craft
Mixed and natural convection flows are often critical to the safety analysis of nuclear reactors. The presence of the buoyancy force and also often the variation in fluid properties such as viscosity and thermal conductivity, due to changes in temperature, further complicate the turbulence structure and make turbulence models currently available in most commercial CFD packages inappropriate.
Over the past several years the Manchester group has developed considerable expertise in the efficient computation of such flows by combining state-of-the-art mathematical models of the turbulent fluctuations with refined and yet computationally efficient approaches to the representation of near-wall turbulence.
The
objective of this project would be to apply and possibly further refine
these approaches to one or more flows relevant to nuclear reactor cooling
applications. Existing, in-house, CFD codes will be used, which are
written in Fortran.
