Description:

This project aims to compare under-floor air distribution (UFAD) and over-head air distribution (OHAD) systems for a model room using computational fluid dynamics (CFD) with respect to:
(i) vertical and horizontal temperature gradients at steady-state,
(ii) vertical and horizontal air velocity gradients at steady-state,
(iii) draught rating at specified room locations at steady-state,
(iv) thermal response times to steady-state, and
(v) the energy requirements to maintain steady-state
