Abstract
The paper presents the investigation of a single microjet cooling forming an thin liquid film on the impingement surface of specially designed rig. The basis of microjet technology is to produce laminar jets, which when impinging the surface have a very high kinetic energy at the stagnation point. Applied technology of jet production can result with the size of jets ranging from 20 to 500μm in breadth and 20 to 100μm in width. Examined is the influence of jet velocity and physical properties. Tests were conducted under steady state conditions, for three fluids namely water, ethanol and HFE7100. Simple empirical correlation has been developed describing Nusselt number on the cooled surface.
