... to 60,000. Heat transfer and pressure drop characteristics studied using computational analysis. Nusselt Number and friction factor of round tube with CTT insert is found to be 1.79–1.94 times and 2.5–3.5 times higher respectively compared to round tube without any insert. Thermal performance factor...

... of both inter-connectors were the same as the mini-channel. Bottom surface temperature, Nusselt number ( Nu ), thermal resistance, and friction factor were calculated to address the effect of the inter-connectors on the overall thermal-hydraulic performance of the heat sink. The results showed that...

Paper No: IMECE2013-63167
... Macroscopic modeling of hydrodynamic behavior of nanofluid flow in a uniformly heated circular pipe is considered. Single-phase models with Brownian and dispersion viscosity models are evaluated by comparing predicted pressure drop and apparent friction factor with experimental and two-phase...

... 12 02 2008 An alternative to the traditional friction factor for pipe flow is presented (φ = [ R ] f ). For incompressible flows, the correlation of this new friction factor with Reynolds Number [ R ] and Relative Roughness [ε] is presented graphically, and appears much simpler and...
