Investigating Flow and Heat Distribution of NE‐PCM in a Double Lid‐Driven MHD Octagonal Chamber

Heat Transfer, Journal Year: 2025, Volume and Issue: unknown

Published: March 20, 2025

ABSTRACT Mixed heat transfer, commonly encountered in engineering applications, has led to a strong focus on maximizing transmission rates. This study explores transfer enhancement within magnetohydrodynamic (MHD) double lid‐driven octagonal cavity. The cavity is filled with porous media and loaded nano‐encapsulated phase change material (NE‐PCM), subjected uniform magnetic field. Galerkin finite element method (GFEM) employed solve the governing equations. Key factors investigated include lid speed (Reynolds number, Re = 1–500), wall movement directions, field intensity (Hartmann Ha 0–100), porosity (Darcy Da 10 −5 –10 −2 ) their effects numerical was validated by comparing results well‐documented data from literature. findings reveal that higher values significantly enhance rates, while reduce Specifically, at highest Re, increasing enhanced averaged Nusselt number ( Nu 165%, 0 100 decreased it 16%. Additionally, moving both walls same direction improved average 350% compared opposing movement. also found NE‐PCM concentration had minimal impact efficiency, reducing chamber permeability hindered suspension movement, thereby between hot cold surfaces.

Direct Current Photovoltaic Solar Energy for Water Heating

Energies, Journal Year: 2025, Volume and Issue: 18(8), P. 2009 - 2009

Published: April 14, 2025

In this study, an experimental device is developed and implemented to evaluate the process of heating water using photovoltaic solar energy in direct current. The prototype consists a 147 L stainless steel tank, 5000 W element, four panels (370 each). Tests were carried out with power supply use maximum point tracking (MPPT) device. Temperature electrical sensors installed connected data acquisition system. results show that produced by PV can be used directly for heating. For supply, average total efficiency 12%; MPPT, value 18.2%. There clear improvement when tracking, improving reducing time needed reach set temperature. This technology applied residences, medical centers, other buildings require it.
