Abstract |
|
In this research paper CFD analysis is carried out of a hot horizontal surface. A horizontal hot plate of 0.25mm thickness at 450â—¦C initial temperature has been quenched by round water jet of 3mm diameter. The Reynolds number is between 3370-24556. The water jet of 3mm diameter impinges normal to the test section of steel. The investigations are made up to 20mm downstream location in upper sides of the stagnation point. It has been observed that during transient cooling, the wetting front velocity increases with the rise in jet velocity and wetting delay decreases with the rise in jet velocity. However rewetting velocity reduces drastically for the extreme downstream locations away from the stagnation point. And wetting delay increases drastically with the rise in jet velocity. |
