I'm new of fluent but I'm trying to simulate a microchannel.(follow this study >>https://drive.google.com/drive/folde...kFTQ1c0a0p5NFE)
My modeling has two zones a solid zone,Copper and the fluid zone,water. These are my boundary conditions. 1.The bottom wall of Copper has constant heat flux = 1,000,000 W/m^2 2.All outside walls of Copper (Except the bottom) are adiabatic walls (Heat flux = 0) 3.The interfaces between the solid and fluid are coupled 4.The inlet is used velocity inlet . 5.The outlet is used pressure outlet.(I didn't type any data in this condition.) So, I found that the summation of the heat of all interfaces equal to the heat from the bottom.It makes sense ! (the heat of an interface = average heat flux that was calculated from the program multiple the area of that interface) But, The temperature on the surfaces looks strange. This picture shows the bottom interface temperature and the bulk temperature (i made the line at middle of fluid) What's wrong with my model ? Thanks in advance for any help that you are able to provide Last edited by zrp3s; November 20, 2016 at 04:15. |
