 October 6, 1999, 00:00 Flow-meter- AGAIN #1 Yogesh Talekar Guest   Posts: n/a Gurus, I am posting this message gain because nobody replied last time! Can any body help me in finding some liturature for a flow-meter. It is actually a pipe of about 1.5 inch diameter with a sensor hanged in about middle of it. This sensor is heated by electrical connections and cools due the flow of gas which flows at maximum speed of 0.5 Mach. The flow is calibrated by the temperature of the sensor. I want to model it using Finite Difference Method? Can I do it as a 2-D flow intially? Are the boundary conditions at the pipe-wall as NO-SLIP conditions? And what are the boundary conditions for the sensor which is hanging in the middle of the pipe? Don't forget to mention the references! Please help me with your valuable suggections. Thank you YOGESH

Any suggections? Thank you YOGESH
