Heat Transfer of an Impinging Jet on a Plane Surface
Abstract—A cold, thin film of liquid impinging on an isothermal hot, horizontal surface has been investigated. An approximate solution for the velocity and temperature distributions in the flow along the horizontal surface is developed, which exploits the hydrodynamic similarity solution for thin film flow. The approximate solution may provide a valuable basis for assessing flow and heat transf...
متن کاملAir entrainment through free-surface cusps.
In many industrial processes, such as pouring a liquid or coating a rotating cylinder, air bubbles are entrapped inside the liquid. We propose that this is due to air being drawn into the narrow channel of a cusp singularity that generically forms on free surfaces. Since the width of the cusp is exponentially small in the driving strength, even the minute viscosity of air is enough to destroy t...
متن کاملMechanism of air entrainment by a disturbed liquid jet
It was shown in recent work that the crests of surface disturbances on a falling jet are a powerful agent for air entrainment at the free surface of a liquid pool. The paper explores the opposite case in which the jet is disturbed so as to form an axisymmetric trough, rather than a crest. It is found that no air is entrained in this case. The paper concludes with some considerations on the vali...
متن کاملModeling Turbulent Entrainment of Air at a Free Surface
Overview In free-surface flows the turbulence in the liquid may be sufficient to disturb the surface to the point of entraining air into the flow. This process is important, for example, in water treatment where air is needed to sustain microorganisms for water purification and in rivers and streams for sustaining a healthy fish population. Air entrainment is typically engineered into spillways...
متن کاملFWm_Generation and Air Entrainment ^''^'^f^tS^ Near a Free Surface %//%
The flow in a breaking wave is a t>'pe of agitation which is conducive to foam formation. The downstream wake of a surface vessel in the seaway also is characterized by a layer of foamy, agitated water near the surface, and a subsurface layer of bubbles or a bubble cloud. The purpose of this report is to discuss the basic features of foam and bubble formation, and air entrainment as these featu...
