☀️ Radiation Heat Transfer
Analyze blackbody emission, view factor algebra, gray surface radiosity networks, radiation shields, and gas mixture emission. Powered by Fortran for precision.
Blackbody Radiation
Stefan-Boltzmann total emissive power, peak Wien wavelength, and Planck's spectral distribution curve comparison.
View Factors Catalogue
Analytical view factors for aligned parallel plates, perpendicular rectangles, coaxial disks, concentric cylinders, and spheres.
Gray Enclosures & Shields
Two-surface gray enclosures with radiosity resistor networks and multi-shield temperature distribution solver.
Gas Radiation (Leckner)
Total emissivity and absorptivity of CO₂ and H₂O combustion gas mixtures with band overlap correction.
Combined Radiation & Convection
Evaluate parallel radiation and convection heat losses from a surface. Compare convective coefficients to linearized radiation coefficients.
Solar Radiation & Position
Calculate solar angles and direct, diffuse, and albedo radiation components on tilted flat surfaces.
Multi-Surface Enclosure (N surfaces)
Solve radiation heat exchange within N-surface gray enclosures using the matrix radiosity method.
Participating Media (Non-Grey)
Evaluate radiation heat transfer and wall net heat fluxes in gaseous combustion enclosures using Leckner's spectral model.
