Heat transfer mechanisms during flow boiling in microchannels
(American Society of Mechanical Engineers, 2004-02)The forces due to surface tension and momentum change during evaporation, in conjunction with the forces due to viscous shear and inertia, govern the two-phase flow patterns and the heat transfer characteristics during ... -
Numerical study of an evaporating meniscus on a moving heated surface
(Journal of Heat Transfer, 2006-12)The present study is performed to numerically analyze an evaporating meniscus bounded between the advancing and receding interfaces on a moving heated surface. The numerical scheme developed for analyzing interface motion ... -
An Experimental investigation of flow boiling characteristics of water in parallel microchannels
(American Society of Mechanical Engineers, 2004-08)Microchannels are being considered in many advanced heat transfer applications including automotive and stationary fuel cells as well as electronics cooling. However, there are a number of fundamental issues from the ... -
On the nature of critical heat flux in microchannels
(American Society of Mechanical Engineers, 2005-01)The critical heat flux (CHF) limit is an important consideration in the design of most flow boiling systems. Before the use of microchannels under saturated flow boiling conditions becomes widely accepted in cooling of ... -
Experimental study of heat transfer in an evaporating meniscus on a moving heated surface
(American Society of Mechanical Engineers, 2005-03)A stable meniscus is formed by a circular nozzle dispensing water over a heated circular face of a rotating cylindrical copper block. The nozzle is offset from the axis of rotation of the copper block and thus a moving ... -
Heat transfer characteristics in partial boiling, fully developed boiling, and significant void flow regions of subcooled flow boiling
(American Society of Mechanical Engineers, 1998-05)Subcooled flow boiling covers the region beginning from the location where the wall temperature exceeds the local liquid saturation temperature to the local where the thermodynamics quality reaches zero, corresponding to ... -
An Experimental investigation on flow boiling of ethylene-glycol / water mixtures
(American Society of Mechanical Engineers, 2003-04)Mixtures of ethylene glycol and water are used in cooling the engines in automotive applications. Heat is transferred essentially under subcooled flow boiling conditions as the mixture flows over the hot surfaces, which ... -
Effects of surface tension and binary diffusion on pool boiling of dilute solutions - An Experimental assessment
(American Society of Mechanical Engineers, 1999-01-13)Pool boiling heat transfer with dilute binary mixtures introduces two additional effects due to binary diffusion, and due to change in the surface tension. The secondary effects due to changes in contact angle and wetting ... -
A Theoretical model to predict pool boiling CHF incorporating effects of contact angle and orientation
(American Society of Mechanical Engineers, 2001-12)A theoretical model is developed to describe the hydrodynamic behavior of the vapor liquid interface of a bubble at the heater surface leading to the initiation of critical heat flux (CHF) condition. The momentum flux ... -
Review of fabrication of nanochannels for single phase liquid flow
(Springer Verlag, 2006-05)Abstract The topic of single phase liquid flow in submicron or nanochannels is a nascent field. There have only been a couple papers that have dealt with this area directly. The most probable reason for this is that ... -
