[ 1 ] - Numerical Investigation on Slot air Jet impingement Heat Transfer between Horizontal Concentric Circular Cylinders
A numerical study has been carried out for slot air jet impingement cooling of horizontal concentric circular cylinders. The slot air jet is situated at the symmetry line of a horizontal cylinder along the gravity vector and impinges on the bottom of the outer cylinder which is designated as θ=0°. The outer cylinder is partially opened at the top with a width of W=30mm and is kept at constant t...
[ 2 ] - Numerical and Experimental Investigations for Design of a High Performance Micro-hydro-kinetic Turbine
Design and manufacturing of a high performance micro-hydro-kinetic turbine is discussed in the present paper. The main goal is manufacturing an equipped experimental model of hydro-kinetic turbine with highest energy absorption from water current. A multi-shape ducted turbine comprised of a multi-part diffuser was manufactured that can be converted to many experimental models for studying vario...
[ 3 ] - Convective Heat Transfer of Oil Based Nanofluid Flow Inside a Circular Tube
Abstract An empirical investigation was carried out to study convective heat transfer of nanofluid flow inside an inclined copper tube under uniform heat flux condition. Required data are acquired for laminar and hydrodynamically fully developed flow inside round tube. The stable CuO-base oil nanofluid with different nanoparticle weight fractions of 0.5%, 1% and 2% was produced by means of ul...
[ 4 ] - Experimental investigation on heat transfer and pressure drop of Al2O3-base oil nanofluid in a helically coiled tube and effect of turbulator on the thermal performance of shell and tube heat exchanger
These days With respect to the high importance of energy concept, limitation of natural resources, regulation of environmental issues, and global warming, heat transfer systemschr(chr('39')39chr('39')) applications get more attention. In the present paper, the experimental effect of Nano-fluid and turbulator on the heat transfer and pressure drop is investigated. AL2O3-SN300 base oil as nanoflu...
