Nanotechnology Research Reveals New Insights on Heat Transfer in Porous Media

Strategic Insights -

Researchers from Zarqa University in Jordan have conducted a study on the comparative heat transfer exploration in the MHD flow of gamma nanoparticles between nonparallel flows for both base fluids, ethylene glycol and water. The examination considered radiation, stretchable walls, and the flow in porous media, highlighting the impact of various factors on velocity, temperature, surface frictional force, and Nusselt number.

Key Takeaways:

  • The study utilized both analytic and computational techniques, including the Daftardar-Jafari method (DJM) to construct an analytical solution for the Jeffery-Hamel problem, and the HAMconstructed Mathematica software and Runge-Kutta Fehlberg 4th-5th order (RKF45) for authorization.
  • The research found that the increment of nanoparticles volume fraction improves Nusselt numbers by up to 18.5% in ethylene glycol instead of water as the base fluid.
  • The study concluded that improving viscous dissipation and radiative fluxing reduces the rates of heat transport in both gamma Al2O3 - H2O and gamma Al2O3 - EG nanofluids.
  • The examination focused on the roles of gal2o3-h2o and gal2o3-eg with thermal radiation on MHD flow across porous stretching-shrinking nonparallel channels.
  • The study was innovative as it employed both analytical and computational techniques, along with a porous radiated channel that contains nanofluid.
  • Additional authors for this research include Ahmed Qazza, Mohamed Kezzar, Mohamed Rafik Sari, Mohamed R. Eid, Essam M. Elsaid, Badria A. A. Yousif, and Sahar Ahmed Idris.

Statistics:

  • The researchers found that the increment of nanoparticles volume fraction improves Nusselt numbers by up to 18.5% in EG instead of water as the base fluid.
  • The study concluded that improving viscous dissipation and radiative fluxing reduces the rates of heat transport in both gamma Al2O3 - H2O and gamma Al2O3 - EG nanofluids by certain percentages.
  • The examination considered the impact of various factors, including Prandtl number, solid volume fraction, base fluid, Darcy number, stretchable walls, and thermic radiative fluxing on velocity, temperature, surface frictional force, and Nusselt number.
  • The study was published in Case Studies in Thermal Engineering, 2025, Volume 73.
