Steady state analysis: Steady state conduction equation in two dimensional cartesian coordinate system is given below: `(del^2T)/(delx^2)+(del^2T)/(dely^2)=0` Upon discretizing the spatial derivatives using central difference scheme, we get: `(T_(i+1,j)-2T_(i,j)+T_(i-1,j))/(Deltax^2)+(T_(i,j+1)-2T_(i,j)+T_(i,j-1))/(Deltay^2)=0`, In the current project, we will simulate flow through a mixing tee using ANSYS for the following three different configurations: (i) Short mixing tee with hot stream entering at `25^oC` and 3m/s and cold stream entering at `10^oC` and 6m/s. Design inputs III. Start Icepak, as described in Chapter 1 of the User's Guide. The macro then exports the resulting temperatures from Icepak back into SIwave, which updates the electrical properties for the DC solution based on the temperature field.
