Numerical simulation of PV/T air collector with gradually expanding and shrinking channels

Evaluation of a PVT Air Collector

Hybrid Photovoltaic Thermal (PVT) collectors are an emerging technology that combines PV and solar thermal systems in a single solar collector producing heat and electricity simultaneously. The focus of this thesis work is to evaluate the performance of unglazed open loop PVT air system integrated on a garage roof in Borlänge. As it is thought to have a significant potential for preheating vent...

Shrinking Hardware, Expanding Interfaces

3D Sensing with MEMS Accurately sensing location in 3D currently requires large, expensive devices. Researchers in MIT’s Department of Aeronautics and Astronautics have devised an approach to microelectromechanical systems (MEMS) fabrication that lets engineers design 3D configurations for existing fabrication processes. They used the approach successfully to build a MEMS device that enables 3D...

Numerical simulation of nanofluids flow and heat transfer through isosceles triangular channels

Nanofluids are stable suspensions of nanoparticles in conventional heat transfer fluids (base fluids) that exhibit better thermal characteristics compared to those of the base fluids. It is important to clarify various aspects of nanofluids behavior. In order to identify the thermal and hydrodynamic behavior of nanofluids flowing through non-circular ducts, in the present study the laminar flow...

Prediction of Entrance Length for Magnetohydrodynamics Channels Flow using Numerical simulation and Artificial Neural Network

This paper focuses on using the numerical finite volume method (FVM) and artificial neural network (ANN) in order to propose a correlation for computing the entrance length of laminar magnetohydrodynamics (MHD) channels flow. In the first step, for different values of the Reynolds (Re) and Hartmann (Ha) numbers (600<ReL increases.
