DOI: 10.1016/j.buildenv.2017.07.030
Abstract: Abstract We demonstrate the use of the ‘Direct-Adjoint-Looping method’ for the identification of optimal buoyancy-driven ventilation flows governed by Boussinesq equations. We use the incompressible Reynolds-averaged Navier-Stokes (RANS) equations, derive the corresponding adjoint equations and… read more here.

DOI: 10.1177/1420326x19833850
Abstract: The task of HVAC systems is to offset indoor thermal and/or ventilation load. Indoor thermal load can be offset by either convective-dominant way or radiantdominant way. In convective dominant way, system recirculated air is thermally… read more here.

DOI: 10.1177/1420326x221119334
Abstract: Compared to traditional theatres, experimental theatres have a lower floor height and the lights are closer to the audience. The large vertical temperature gradient caused by the underfloor air distribution (UFAD) system extremely impairs thermal… read more here.
