Numerical Simulation of 2D Flow through a Packed Bed of Square Cylinders
Ferreira de Sousa, Paulo J. S. A.; Malico, Isabel; Fernandes, GérsonThis paper is centred on a compact finite differences method for the calculation of two-dimensional viscous flows through complex geometries. The immersed boundaries are set through body forces that allow for the imposition of boundary conditions that coincide with the computational grid. Two different flow configurations are simulated. First, the flow past a cylinder with square cross-section inside a plane ch...
Analysis of a photovoltaic unit using computational fluid dynamics
Fernandes, Gérson; Malico, Isabel; Ferreira de Sousa, Paulo J. S. A.; Pina, LuísThe use of photovoltaic panels is rising, and its use will play a significant role in achieving the European Union’s target of 20% of energy consumption coming from renewable resources. At the same time, suppliers of solar energy panels aim to optimise the use of photovoltaic cells. This can be done, for example, by using intelligent methods of cooling to gain the maximum electrical output possible, and minimiz...
2D Flow in a Wall-bounded Porous Medium
Ferreira de Sousa, Paulo; Malico, Isabel; Fernandes, GérsonA compact finite differences method is used to calculate two-dimensional viscous flows through complex geometries. The immersed boundaries are set through body forces that allow for the imposition of boundary conditions that coincide with the computational grid. Two different flow configurations are simulated. First, the flow through a row of cylinders with square cross-sections is calculated and used as a vali...
