Technical note: Numerical analysis of two dimensional parallel Flow flat-plate solar collector

摘要

Temperature distribution over the absorber plate of a parallel flow flat-plate solar collector is analyzed with one-and two-dimensional steady-state conduction equations with heat gener- ations. The governing differential equations with boundary conditions are solved numerically using a control volume-based finite difference scheme. Comparisons of one-and two-dimen- sional results showed that the isotherms and performance curve, stated in terms of an effectivenessumber-of-transfer-unit relationship, for one-dimensional analysis slightly devi- ate from that of two-dimensional analysis, particularly under low mass flow rate conditions.
