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 ...
LAMINAR AIR FLOW FREE CONVECTIVE HEAT TRANSFER INSIDE A VERTICAL CIRCULAR PIPE WITH DIFFERENT INLET CONFIGURATIONS
laminar flow free convective heat transfer vertical pipe
2009/10/14
Free convection heat transfer has been experimentally investigated for laminar air flow in a vertical circular pipe by using the boundary condition of constant wall heat flux in the ranges of RaL from...
风筛式清选装置非均布气流清选原理与试验（Theory and Experiment on Non-uniform Airflow Cleaning of Air-screen Cleaning Unit）
联合收获机 清选 非均布气流
2009/5/22
脱出物从横置的轴流式脱粒装置下落到纵置的清选筛上时，在筛面入口段堆积成堆影响清选。提出了非均布气流清选原理，设计了圆锥形离心风扇以产生非均匀气流。理论分析和试验验证表明：由圆锥形离心风扇大、小端的直径差形成的非均布气流产生了风压差，使振动筛前部出现了较大的横向风速(最高处2.6m/s)，将下落中的脱出物向另一端吹送，使脱出物在振动筛面的初始分布明显改观，从而改善了横置轴流式全喂入联合收获机的清选性...
