| Abstract: |
| In the present research, a square microchannel with a T connection with a hydraulic diameter of 1 mm is initially prepared and meshed in ANSYS. Fluid inlets are created at a 90 degree angle. The length of the square fluid inlets is 2 mm. The length of the mixing zone is kept at 150 mm so that the mixing effect of the two fluids can be easily obtained and the fully developed flow can be observed. The longer channel length also allows observation of bubble size stability and uniformity over multiple flow conditions. The junction T is shown in the 3D microchannel. Weather is considered as the working fluid. Finally, the results showed that the bubble formation time increases with the increase of the connection angle. Also, the results show that with the increase in water speed, the length of the created bubble decreases and the bubble becomes smaller. According to the diagram of the dimensions of the formed bubble, the largest dimensions in the formed bubble for the connection angle schematic are 90 degrees. According to the diagram of the fluid pressure inside the microchannel and the shape of the contours taken from the schematic, it can be seen that the pressure at the entrance of the model and the connection area is the highest. |
