A New Principle for Building Simulation of Radiative Heat Transfer in the Presence of Spherical Surfaces

Abstract: Radiant heat interchanges are pivotal to assessing the energy use of buildings and facilities that channel some sort of solar radiation. Form factor integrals are needed for an accurate simulation of the main features of the envelope of such buildings. However, the expressions required when the space under analysis is curved, for instance, in domes and vaults, are not feasible. The calculation process of algorithms is usually addressed by cumbersome analytical deductions or else by rough statistical approximat… Show more

“…With a similar approach, the total form factors are found for the usual sets of precincts, such as prisms or oblique cuboids. Inter-reflection within the so-generated space is also an issue that we have to foresee; in the case of triangular prisms, we would require a set of five equations with five unknowns, which is detailed in the Appendix A [27].…”
