Experimental Investigation on Pouring Aggregate to Plug Horizontal Tunnel with Flow Water

Experimental Investigation on the Effect of Parameters Influencing the Performance of a Horizontal Styrene-Water Separator

Experimental Investigation on Air-Water Interaction in a Hydropower Station Combining a Diversion Tunnel with a Tailrace Tunnel

Diversion tunnels are often used as tailrace tunnels in underground hydropower stations. The special layout results in complex flow regimes, including air-water two-phase flow. A set of experiments is conducted based on the model of a hydropower station which combines partial diversion tunnels with tailrace tunnels to investigate the interactions between the air and water phases in the combined...

Experimental Investigation of Surface Roughness Effect on Flow Boiling in Internal Combustion Engine Water Jacket

The subjects of heat transfer and cooling system are very important topics in the Internal Combustion Engines (ICE). In modern cooling systems, low weight, small size and high compactness are the critical designing criteria that requires heat transfer enhancement. Boiling phenomenon which is occurred in the water jacket of the ICE is one of the methods to increase heat transfer in the coolant s...

Experimental investigation of shear-driven water film flows on horizontal metal plate

In this article, an experimental investigation has been conducted to characterize the instantaneous thickness of the surface water film driven by high-speed airflow pertinent to aerodynamic icing and anti-icing modeling. Non-intrusive results of the film flowing on a metal plate were obtained using the high-speed camera and confocal chromatic technique. The wind speed (Ua) ranges from 17.8 m/s ...

EXPERIMENTAL INVESTIGATION OF EFFECTS OF WALL POROSITY AND SUCTION ON THE FLOW QUALITY IN A TRANSONIC WIND TUNNEL

A trisonic wind tunnel has been modified to improve its flow quality when operating at transonic speeds through perforated walls and side suctions. The usefulness of such a perforated wall, already known, is reduction of the blockage effect as well as the shock elimination. Two types of perforated walls have been used in this investigation. The first wall had a porosity of about 22% and the hol...
