Path: Thermal/HeatTransfer
% Computes temperatures on a radiation shield with MLI Uses fzero to solve for the surface temperature. Type RadiationShield for a demo. Surface coefficients are white paint. -------------------------------------------------------------------------- Form: d = RadiationShield % data structure [tS, tI] = RadiationShield( d ) -------------------------------------------------------------------------- ------ Inputs ------ d (.) Input data structure .n (1,1) Number of layers of MLI .cS (1,1) Conduction coefficient .cR (1,1) Radiative coefficient .gamma (1,1) Conduction exponent .epsTR (1,1) Effective emissivity .alphaS (1,1) Surface absorption coefficient .epsS (1,1) Surface emittance coefficient .epsI (1,1) Emissivity of inner wall .qS (1,1) Surface flux (W/m^2) - default is sun .tol (1,1) Tolerance for iteration on temperature ------- Outputs ------- tS (1,1) Surface temperature (K) tI (1,1) Inner wall temperature (K) qI (1,1) Flux from inner wall (W/m^2) k (1,1) Conductance (W/m^2 K) out (.) Output data .err (1,1) Error in RHS .nD (1,1) MLI density (layers/cm) .qMLI (1,1) MLI heat flux (W/m^2) -------------------------------------------------------------------------- See also: OptimalMLIDensity --------------------------------------------------------------------------
