Cooling photovoltaic panels with air convection – Parametric environmental and economic analysis with case studies

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Photovoltaic (PV) panels generate electricity due to photoelectric effect, harvesting solar radiation from the sun. However, the hit of photons on the upper surface of the PV panel increases its temperature, and as a result, decreases its efficiency. The

USING MODES OF FREE OSCILLATION OF A ROTATING VISCOUS FLUID IN THE LARGE-SCALE DINAMO [PDF]

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2013
Considered a model of large-scale magneto-convection in a roteting spherical shell. Velocity expressed of the one of the modes of free oscillation of a viscous conduction fluid in the shell. The stationary modes of convection were found.

3D Printing Innovations in Polymeric Porous and Patterned Architecture

Advanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Enhanced visualisation of complex thermofluid data: Vertical and horizontal combined convection and microscale heat transfer cases [PDF]

, 2000
Copyright @ 2000 UITIn general, convective heat transfer is an 'n-dimensional' problem where n is well in excess of 3 for steady flows. Traditionally, the method of dimensional analysis results in a small number of dimensionless groups.

Natural convection heat transfer from two horizontal cylinders

, 2008
Natural convection heat transfer from a single horizontal cylinder and a pair of vertically aligned horizontal cylinders is investigated. Surface heat transfer distributions around the circumference of the cylinders are presented for Rayleigh numbers of ...

Transition of thermally induced flow in a square cavity using Spectral Method [PDF]

E3S Web of Conferences
This study presents a novel mesh-free method for simulating natural convection in a square cavity filled with Newtonian fluid. The proposed algorithm integrates mesh-free Spectral methods with the Moving Collocation Element (MCOE) technique and employs a

Spatially Decoupling Heating and Evaporation for Convection‐Enhanced 3D Solar Evaporation With Continuous Salt Harvesting

Advanced Functional Materials, EarlyView.
An architecture‐enabled bottom‐heated 3D solar convective evaporator spatially decouples photothermal heating from evaporation, triggering natural convection that intensifies sidewall vapour removal and heat transfer. The system achieves significantly enhanced evaporation rates over 2D and conventional 3D designs while confining salt precipitation to ...
