Program Purpose:

Price Industries is a market leader in supplying air distribution, critical controls and noise control products. Onex000D
of their products, a chilled beam, is a cooling/heating device that uses high velocity nozzles to draw room airx000D
through an air/water heat exchanger. It is important to achieve as much mixing of the air through the coil asx000D
possible so Price Industries is interested in changing the shape of the nozzles from a traditional circular shapex000D
to optimize the design of the chilled beam unit. They have recently conducted physical experiments tox000D
investigate the effect of nozzle shape on the air flow, which has proven to produce very complex turbulent flowx000D
fields. Price has a dedicated team that uses Computational Fluid Dynamics (CFD) to validate the design of airx000D
distribution systems in a wide range of commercial and industrial spaces and for innovative research productx000D
development support. It is important for the company to be able to accurately predict the flow from the nozzlex000D
in a chilled beam in order to simulate the air distribution system using CFD. It is unlikely that the simplex000D
turbulence model that Price currently uses in their CFD simulations will be able to capture the complexx000D
turbulent flow that is produced from a non-circular jet. Price requires some investigation and guidance on thex000D
most effective and efficient CFD method in order to accurately capture this complex flow field. This researchx000D
will evaluate the effectiveness of several CFD methods for modelling the nozzle outflow for various nozzlex000D
shapes and provide recommendations to improve the CFD modelling for the chilled beam nozzle design. Thisx000D
work will support Price Industry by potentially reducing the time required to introduce new HVAC products tox000D
the market as new designs can be tested first using numerical simulations using their improved CFDx000D
methodology.
