Hi,

I am supposed to do an analysis of two fluid cross flow plate fin type heat exchanger for my college project.
The heat exchanger is insulated from the surroundings. The heat exchanger is investigated for step perturbations provided in hot fluid inlet temperature. The corresponding response at the outlet of cold fluid is studied.
Can anyone tell me what software should I use for the analysis and post me a tutorial to understand the process?
Thanks

Hi, i knew someone that studied something similar using Ansys. Never used it myself but should be straightforward and a lot of other ppl use it.

If you have access to comsol you can search the crossflow heat exchanger tutorial between the case files that are included in the installation, it uses a similar similar geometry, with five cold channels and five hot channels stacked one over the other.

how can I make a duplicate mesh in the structure and not duplicate in the fluid in the GMSH?
Geometry is the cross section of the guitar, I'm having trouble putting just fluid in the sound hole of the guitar.

and I need the mesh to be triangular regular


between point(4) and point (5), it's the sound hole, and there I need it to be just fluid and the line(4) disappears.

help me please, i'm beginner of scientific research


msh code .geo

dim = 34;
gridsize = dim/4;

dim2 = 38.3;
gridsize2 = dim2/4;

dim3 = 48;
gridsize3 = dim3/4;


Point(1) = {0, 0, 0, gridsize};
Point(2) = {dim3 , 0, 0, gridsize3};
Point(3) = {dim3 , 10.5, 0, gridsize3};
Point(4) = {dim2, 10.5, 0, gridsize2};
Point(5) = {dim, 10.5, 0, gridsize};
Point(6) = {0, 10.5, 0, gridsize2};

Line(1) = {1, 2};

Line(2) = {2, 3};
//+
Line(3) = {3, 4};
//+
Line(4) = {4, 5};
//+
Line(5) = {5, 6};
//+
Line(6) = {6, 1};

Line Loop(1) = {6, 1, 2, 3, 4, 5};

Plane Surface(1) = {1};
