A CFD ANALYSIS OF ROOM ASPECT RATIO ON THE EFFECT OF BUOYANCY AND ROOM AIR FLOW
aspect ratio room airflow buoyancy comfort
2009/10/14
Comfort conditions in air-conditioned rooms require that temperature in the occupied zone should not vary by more than 1 °C and velocity, every where in the room, should be less than 0.15 m/s so that ...
Estimation of Uncertainty of Air Buoyancy Correction for Establishment of Primary Mass Standards
air density air buoyancy correction primary mass standard
2009/10/14
The most accurate value of air density is obtained by a calculation based on the equation using measured atmospheric parameters approved by the International Committee for Weights and Measures in 1981...
Importance of Buoyancy and Chemistry Modelling in Steady RANS Simulations of Well-Ventilated Tunnel Fires
Tunnel fire Critical ventilation velocity Buoyancy modelling Chemistry modelling Steady simulations
2009/10/10
Numerical CFD simulation results are presented for well-ventilated fires in horizontal tunnels. Simulations are performed in the framework of steady Reynolds-Averaged Navier-Stokes modelling. As a tur...
