New Nanoparticles Study Findings Recently Were Reported by Researchers at COMSATS Institute of Information Technology

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Nanoparticles have been published. According to news reporting out of Islamabad, Pakistan, by NewsRx editors, research stated, "This study investigates the magnetohydrodynamic (MHD) flow of ferrofluid along a stretching cylinder. The velocity slip and prescribed surface heat flux boundary conditions are employed on the cylinder surface."

Our news journalists obtained a quote from the research from the COMSATS Institute of Information Technology, "Water as conventional base fluid containing nanoparticles of magnetite (Fe3O4) is used. Comparison between magnetic (Fe3O4) and non-magnetic (Al2O3) nanoparticles is also made. The governing non-linear partial differential equations are reduced to non-linear ordinary differential equations and then solved numerically using shooting method. Present results are compared with the available data in the limiting cases. The present results are found to be in an excellent agreement. It is observed that with an increase in the magnetic field strength, the percent difference in the heat transfer rate of magnetic nanoparticles with Al2O3 decreases."

According to the news editors, the research concluded: "Surface shear stress and the heat transfer rate at the surface increase as the curvature parameter increases, i.e curvature helps to enhance the heat transfer."
