    Surface temperature Calculations (HX)

    Energy balance eq in case of heat conduction through Fin; In fin case, the total area is considered carefully as area of conduction isn't simple. Energy balance eq in case of heat transfer through tube; The total thermal resistance is combination of conduction and convection. By solving...

    Surface temperature Calculations (HX)

    HI rackoope I have attached some rough diagrams of the arrangement of the tube & other stuff. I think you can get some good idea from this scenario. Thanks

    Surface temperature Calculations (HX)

    I am uncertain about the energy balance equation because that's according to the geometry of surface. I think i might have not included some aspect of surface or something is missing while taking account all factor in above mentioned equations.That's why the outlet temp isn't correct. Eventually...

    Surface temperature Calculations (HX)

    My question is regarding surface temperature, i already have posted the equations. And mostly calculations are about the basic thermodynamic analysis. The crux of this problem is that the solar radiations hit on surface and i need to know best approach to calculate the surface temperature? What...

    Surface temperature Calculations (HX)

    DNI of any particular area varies with time so i am considering peak average flux 800w/m^2. The allowable peak flux for various HTF is different and in my case,considering water as HTF so 0.2MW/m^2 is valid. If you have solar field of 700 heliostats with surface area of 7.2m^2 and concentration...

    Surface temperature Calculations (HX)

    It's not for school. It's about thermodynamic analysis for designing of Tubular solar thermal receiver(Thermal rating 3.3 MW). Thanks

    Surface temperature Calculations (HX)

    Hi, Could anyone please help me regarding calculating the surface temperature of HX tube and tubes are covered by aluminium sheet? In this case, the 5.02m^2 area is exposed to sun, 500kW/m^2 peak flux on surface, total no of tubes 20 are arranged in parallel manner in one row (parallel flow)...
