Flow and heat transfer characteristics of high temperature continuous rising bubbles

In the movement process of continuous bubbles, different liquid-flow state and initial temperature bubbles have important influence on bubble heat transfer. this study, flow transfer characteristics high in normal liquid are investigated. The rising studied by numerical simulation compared with experimental results for verification. show that shape, velocity affected position bubble. Because closer is to bottom cylinder, greater decrease aspect ratio, w*, faster temperature, larger would be. increase diameter mitigate jet motion. Finally, as surface tension increases, less movement.
