Study of photonic radiative coolers based on semispheres for silicon photovoltaic cells
(Optica Publishing Group, 2022)
Conference report
Restricted access - publisher's policyWe propose a photonic structure of semispheres for radiative cooling of silicon photovoltaic cells. Two materials are studied numerically: soda-lime and polydimethyl-siloxane. Results show an output power increment of ~ ... -
Heat Transfer Modeling in Server Refrigeration: A 0D-1D Transient Box
(Purdue University, 2024)
Conference report
Open AccessA 0D-lD transient and computationally inexpensive model is used to simulate the thermal behavior of a server that is placed in an exterior environment. This model consists of N-interconnected boxes that are modeled with a ... -
Lightweight AMG preconditioners for CFD simulations on symmetric domains
(2024)
Conference report
Open AccessDivergence constraints appear in the governing equations of many physical phenomena, often leading to a Poisson equation whose solution is one of the most challenging parts of incompressible CFD codes. Algebraic Multigrid ... -
Mathematical and Numerical Approach of Encapsulated Phase Change Material in Structured Thermocline Systems
(2024)
Conference report
Open AccessAn unsteady one-dimensional computational model has been developed to investigate the integration of encapsulated phase change materials in a structured thermal energy storage system. The model has been validated against ... -
On the Conditions for a Stable Projection Method on Collocated Unstructured Grids
