The growth of a single microscopic water vapor bubble under low-pressure condition at the heated surface is investigated experimentally. Details about the shape development of the bubble and velocity of the interface are studied using an image-processing scheme specifically developed for this purpose. The interface velocity is evaluated using an optical(More)
This work is devoted to the numerical simulation of liquid-gas flows. The liquid phase is considered as incompressible, while the gas phase is treated as compressible in the low Mach number approximation. A single fluid two pressure model is developed and the front tracking method is used to track the interface. Navier-Stokes equations coupled with that of(More)
Using high speed video camera and numerical processing of the digital images transient description of the geometry and the interface velocity for vapour bubble growing at the heated surface is achieved. Particle Image Velocimetry and Thermometry are applied to obtain details about velocity and temperature in the surrounding flow field.
An experimental investigation of a vapour bubble growth is performed for water boiling inside a small cube shaped cavity under subatmopsheric pressures. Generation of an isolated bubble is achieved by concentrating heat flux on a small metallic area at the center of the horizontal surface. Bubble growth, recorded using a high speed camera (4500 frames/s),(More)
