Simulation and Analysis of T-Junction Microchannel

Microelectromechanical (MEMS) bring the great revolution in microfluidics. Particularly microchannels are extensively studied in last few years. This paper presents the microfluidic analysis of T-junction type microchannel. ANSYS has been used for microfluidic analysis. The length of microchannel is 1000 µm and length of T-junction is 500 µm. The diameter of microchannel is 100 µm. The velocity and fluid flow variation through the T-junction have been analyzed in computational fluid dynamic (CFX) environment at applied pressure of 100 kPa, 200 kPa and 300 kPa. The maximum velocities vector at the T-Junction walls 3.910e1, 5.701e1 and 7.734e1 have been achieved. The flow rates of 341, 572 and 673 mL/min have been observed through the microchannel with diameters of 100 µm
