In this work, it is a numerical study of the dynamic and thermal behavior of two counter-current flows of a fluid in a heat exchanger. The exchanger has the shape of two rectangular channels of height H separated by an exchange surface through which the exchanges between the two fluids take place by conduction and of the same length L. We have written the transfer equations which govern our problem by closing it with the boundary conditions. To solve it, we used the finite volume method and wrote a calculation code under Ansys-Fluent. We have determined the variation of isotherms and isocurrents in the exchanger and the variation of the temperature on the exchange wall. |
