WebCharacteristics of Trailing Bubble Velocity in Consecutive Large Bubbles Rising through a Inclined Tube. N. Nakamura, Y. Hirose, Takeyuki Ami, H. Umekawa, M. Ozawa. Engineering, Physics. 2013. In this study, the rising velocity of Taylor bubbles in inclined tube was investigated. In the experiment, the air-water two-phase flow system equipped ... Webthe entrance effect correction. However, certain factors can affect so that the entrance pressure drop values obtained using zero-length capillary become unrealistically high. Probably the most important one is the fact that if the melt extrudate sticks to the walls of the capillary exit region, it causes an extra viscous flow

WebMay 22, 2024 · The internal flow configuration is a convenient geometry for heating and cooling fluids used in energy conversion technologies such as nuclear power plants. For internal flow regime an entrance region is typical. In this region a nearly inviscid upstream flow converges and enters the tube. WebThe exit loss is associated with liquid flow from a pipe into a large tank as shown in Figure 4.4. As the liquid enters the tank, its velocity is decreased to very nearly zero. Similar to entrance loss, the exit loss can be calculated as. Sign in … ray winney
