A Mathematical Study of Rectangular and Triangular Fins with Variable Thermal Conductivity Through Local Thermal Equilibrium and Local Thermal Non-Equilibrium Fluid Models by Means of Artificial Neural Network

A mathematical approach is employed to examine the heat transmission capabilities of rectangular and triangular porous fins in both Local Thermal Equilibrium (LTE) and Local Thermal Non-Equilibrium (LTNE) scenarios. To provide a more accurate depiction of the thermal interaction between the solid and fluid phases, the LTNE model uses two coupled energy equations to represent their respective temperature fields. In contrast, the LTE model is controlled by a single energy equation and assumes a co
