Ts = 50; % surface temperature (°C) Tinf = 20; % fluid temperature (°C) uinf = 5; % fluid velocity (m/s) L = 1; % plate length (m) W = 0.5; % plate width (m)

% Given Data kA = 10; LA = 0.1; kB = 1; LB = 0.05; T1 = 300; h = 10; Tinf = 20; % Resistances RA = LA / kA; RB = LB / kB; Rconv = 1 / h; % Heat Flux calculation q = (T1 - Tinf) / (RA + RB + Rconv); % Interface Temperature (T2) % T1 - T2 = q * RA T2 = T1 - (q * RA); fprintf('The interface temperature is %.2f C\n', T2); Use code with caution. % Define the thermal diffusivity, radius, and initial

We first define our physical constants and grid points in MATLAB. Step 2: Solve System

Analyzing how temperature changes over time, often using the Finite Difference Method (FDM) or Finite Element Analysis (FEA). 2. Convection Conduction % Solving Laplace Equation on a 2D

Key values include the heat transfer coefficient ( ) and the Nusselt number (

Always verify the Fourier stability criterion ( ny = 20

Before writing code, we must understand the core mathematical models for each mode of heat transfer. 1. Conduction

% Solving Laplace Equation on a 2D Plate nx = 20; ny = 20; T = zeros(nx, ny); % Boundary Conditions T(:,1) = 100; % Left side T(:,end) = 0; % Right side T(1,:) = 0; % Top T(end,:) = 0; % Bottom % Iterative Solver (Gauss-Seidel) for iter = 1:1000 for i = 2:nx-1 for j = 2:ny-1 T(i,j) = 0.25*(T(i+1,j) + T(i-1,j) + T(i,j+1) + T(i,j-1)); end end end contourf(T); colorbar; title('Temperature Distribution'); Use code with caution.
