In the work presented are thermal and hydraulic problems concerned with the liquid films formed by impinging jets. Formulated has been a simple two-dimensional model of the flow and heat transfer in the film. The model is based on simplified equations of mass, momentum and energy balance. Solution of such set of equations enables determination of velocity profile in the film as well as local heat...
In the paper the results of experimental investigations concerning the hydraulic jump formed by an aerosol impinging jet have been presented. Results of carried out experiments yield that aerosol impinging jet enables to form significantly higher diameter of the hydraulic jump, as compared with single phase, liquid impinging jet. This is caused by shear stresses, between liquid layer, formed by liquid...
In the paper theoretical analysis of the phenomenon of impingement of a circular liquid jet upon a plate has been carried out. In the considered case, spreading of the liquid on a plate is caused by the inertia and gravity forces. For supercritical liquid flow, in certain conditions a hydraulic jump is formed. The circular hydraulic jump exhibits behaviour quite different from that commonly observed...
