  • Abstract The high performance cooling system is the technology we need
    imminently today. It been known recently that si- gnificant
    heat transfer enhancement can be achieved using laminar non-
    Newtonain fluids in a non-circular duct. The objectives of the
    present study is to investgate the inf- luence of variables
    viscosity of temperature-dependent Newtonial fluids and non-
    Newtonial fluids on laminar heat transfer in a triangular duct.
    In the present study, both numerical simulation and
    experimental research will be conducted for studing the heat
    transfer enchancement. First, numerical studies for temperature-
    dependent viscosity Newtonian fluid and top wall heating are
    proformed. It is found that the velocity profile is distorted
    toward the corner of highest temper- ature zone. So the
    influnce of temperature is good to the heat transfer
    enchancement for water. Then Corbopol will be the non-Newtonial
    sample of study objective. And it is found that too strong
    shearthinning effect will reduce the efficiency of triangular
    ducts with uniform top heating. cooling system. The
    experimental research will check the accurency of the numerical
    method for water and corpobol fluid. It is proved that the
    accurency is acceptable. And found the efficiency of corbopol's
    cooling system is better then water's.
