A Theoretical Investigation on Thermal Entrance Region Heat Transfer in a Conduit Filled with Nanofluids
A theoretical analysis has been made to explore thermal entrance region heat transfer in nanofluids. The numerical model used in this paper is based on the Buongiorno model for convective heat transfer in nanofluids with modifications to fully account for the effects of nanoparticles volume fraction distributions on the continuity, momentum and energy equations. Numerical investigations have be...
متن کاملFluid Flow and Heat Transfer of Nanofluids over a Flat Plate with Conjugate Heat Transfer
The falling and settling of solid particles in gases and liquids is a natural phenomenon happens in many industrial processes. This phenomenon has altered pure forced convection to a combination of heat conduction and heat convection in a flow over a plate. In this paper, the coupling of conduction (inside the plate) and forced convection of a non-homogeneous nanofluid flow (over a flat plate) ...
متن کاملHeat Transfer from a Tube Bank in Cross Flow in a Duct
An experimental investigation on heat transfer coefficient is presented from three horizontal tubes in a vertical array in a duct for 500<ReD<6000. A mass transfer measuring technique based on psychrometry chart is used to determine heat transfer coefficient. The diameter of the tubes is 11 mm each spaced 40 mm apart and in-line pitch ratio varies 
in the range 0.055<D/W<0.22. The experimen...

متن کاملMeasurement of Heat Transfer in the Entrance Region of Small Diameter Tubes
Heat transfer coefficient in the entrance region of water flowing through micro-tubes with diameters of 962 μm and 123 μm was investigated in this study. Two temperature measurement methods, thermocouple and liquid crystal thermography (LCT), were used to measure the tube surface temperature. The experimental data showed that the Nu in the entrance region can be predicted well by conventional c...
