Journal ArticleDOI
Numerical simulation of parabolic trough solar collector: Improvement using counter flow concentric circular heat exchangers
TL;DR: In this article, the thermal and fluid-dynamic behavior of a single-pass and double-pass solar parabolic trough collector is analyzed in the presence of recycle at the ends.
Journal ArticleDOI
Numerical simulation of a Linear Fresnel Reflector Concentrator used as direct generator in a Solar-GAX cycle
TL;DR: In this paper, a detailed one-dimensional numerical simulation of the thermal and fluid-dynamic behavior of a Linear Fresnel Reflector Concentrator (LFRC) is presented.
Journal ArticleDOI
Numerical simulation of triple concentric-tube heat exchangers
TL;DR: In this paper, a detailed one-dimensional steady and transient numerical simulation of the thermal and fluid-dynamic behavior of triple concentric-tube heat exchangers has been developed, where the governing equations (continuity, momentum and energy) inside the inner tube and the annulus (inner and outer), together with the energy equations in the inner, intermediate and outermost tube wall and insulation, are solved iteratively in a segregated manner.
Journal ArticleDOI
Numerical simulation and experimental validation of coiled adiabatic capillary tubes
TL;DR: Garcia-Valladares et al. as mentioned in this paper extended and validated the model developed and presented in previous works to coiled adiabatic tube expansion devices working with pure and mixed refrigerants.
Journal ArticleDOI
Numerical simulation of double-pipe condensers and evaporators
TL;DR: In this article, a detailed one-dimensional steady and transient numerical simulation of the thermal and fluid-dynamic behavior of double-pipe heat exchangers (evaporators and condensers) has been carried out.
