Turbulent Events and Gas-Side Mass Transfer Coefficients in a Wavy Air-Water Stratified Flow

Turbulence structure on the gas side of a wavy stratified flow was experimentally investigated in a near horizontal 18.7 cm (H) 10 cm (W) 5.5m (L) rectangular duct.By applying the Variable Interval Time Averaging (VITA) technique to the hot wire anemometer measurements frequency of occurrence of turbulent events were detected near the air-water interface. Experimental results showed that fr...

Experimental measurement of heat transfer coefficient and mass of deposited CaSO4 in subcooled flow boiling condition

Fouling is a common, fundamental and costly problem in heat transfer systems, which reduces thermal efficiency of equipment, increases the energy loss and causes strong damage to the heat transfer equipment in various industries. The main causes of fouling on the heat transfer surfaces are salts with inverse temperature-solubility in the fluid which calcium sulfate is one of the most important ...

Flow Air And Gas Exhaust Fan Drive Unit Anechoic Test Chamber Flow Management System

The features of the data acquisition and control systems of the NASA Langley Research Cen-ter's Jet Noise Laboratory are presented. The Jet Noise Laboratory is a facility that simulates realistic mixed ow turbofan jet engine nozzle exhaust systems in simulated ight. The system is capable of acquiring data for a complete take-oo assessment of noise and nozzle performance. This paper describes th...

Flow Analysis Heat and Mass Transfer in a Room

This reports the study on the flow behaviour, heat transfer and contamination distribution in a room. For this purpose the 3-D incompressible Navier-Stokes equations, energy equation and a mass transfer equation which model the concentration of contamination have been applied. For turbulence simulation the two equation standard k-  turbulence model was employed. By means of SIMPLE algorithm the...
