kd2Tdx2+q̇=0k the fraction with numerator d squared cap T and denominator d x squared end-fraction plus q dot equals 0 = Thermal conductivity (W/m·K) = Temperature (K) = Position (m) = Volumetric heat generation rate ( W/m3W/m cubed Practical Example Consider a plane wall of thickness with a thermal conductivity . The left surface ( ) is held at , and the right surface ( ) is held at . The wall generates internal volumetric heat at a rate of
A=0.5; eps=0.8; Ts=350; Tsur=300; h=10; sigma=5.670374e-8; Qconv = h*A*(Ts-Tsur); Qrad = eps*sigma*A*(Ts^4 - Tsur^4); Qtotal = Qconv + Qrad; fprintf('Qconv=%.2f W, Qrad=%.2f W, Qtotal=%.2f W\n',Qconv,Qrad,Qtotal); Use the MathWorks File Exchange to find thousands
Heat transfer rate per unit area = 600 W/m^2
q=kA(T1−T2)Lq equals the fraction with numerator k cap A open paren cap T sub 1 minus cap T sub 2 close paren and denominator cap L end-fraction MATLAB Example: Temperature Profile in a Composite Wall Consider a furnace wall made of two layers: Firebrick ( m) and Insulating brick ( m). The inner surface is at 1000∘C1000 raised to the composed with power C and the outer surface is at 50∘C50 raised to the composed with power C The wall generates internal volumetric heat at a
Let's examine representative solved problems that illustrate how MATLAB handles different heat transfer scenarios.
hx=Nux⋅kfluidxh sub x equals the fraction with numerator Nu sub x center dot k sub fluid end-sub and denominator x end-fraction Practical Example 20∘C20 raised to the composed with power C flows at a velocity of over a flat electronic component board. The board is long and is maintained at 60∘C60 raised to the composed with power C . Air properties at film temperature are: The board is long and is maintained at
: Discretizing the rod and applying the finite difference method where until convergence. www.mchip.net Example: Transient Cooling (Lumped Capacitance)
ρVCpdTdt=−hAs(T−T∞)rho cap V cap C sub p the fraction with numerator d cap T and denominator d t end-fraction equals negative h cap A sub s open paren cap T minus cap T sub infinity end-sub close paren MATLAB Implementation
Heat transfer isn’t about having the most files – it’s about understanding the physics. And MATLAB is the perfect tool for that.
