Computerized Thermal Conductivity of Liquid
SKU: HI MHM-007

The "HANSA" heat transfer trainer offers basic experiments for targeted teaching on the topic of heat conduction in fluids. Such teaching should discuss the fundamental differences between gases and liquids.Two cylinders form the main component of the experimental unit: an electrically heated inner cylinder situated in a water-cooled outer cylinder. There is a concentric annular gap between the two cylinders. This annular gap is filled with the fluid being studied. The heat conduction occurs from the inner cylinder, through the fluid to the outer cylinder. The narrow annular gap prevents the formation of a convective heat flux and allows a relatively large pass-through area while at the same time providing a homogeneous temperature distribution.The experimental unit is equipped with temperature sensors inside and outside of the annular gap. Thermal conductivities for different fluids, e.g. water, oil, air or carbon dioxide can be determined in experiments.The microprocessor-based instrumentation is well protected in the housing. The software consists of a software for system operation and for data acquisition and an educational software.Computerized Thermal Conductivity of LiquidFEATURESSteady heat conduction in gases and liquids:Determine the thermal resistance of fluidsDetermination of thermal conductivities k for different fluids at different temperaturesTransient heat conduction in fluids:Interpret transient states during heating and coolingIntroduction to transient heat conduction with the block capacity modelFunctions of the software: educational software, data acquisition, system operation SPECIFICATIONConcentric annular gap between 2 cylinders containing the fluid being studiedInner cylinder, continuously electrically heatedWater-cooled outer cylinderHeaterHeating power: 350WTemperature limitation: 95?CHeat transfer area: 0,007439m2Annular gapHeight: 0,4mmAverage diameter: 29,6mmInner cylinderMass: 0,11kgSpecific heat capacity: 890J/kg*KMeasuring rangestemperature: 2x 0?325?CHeating power: 0?450WRequired for Operation230V, 50Hz, 1 phase230V, 60Hz, 1 phase; 120V, 60Hz, 1 phase DIMENSIONS AND WEIGHTLxWxH (approx.): 800x600x500mmWeight (approx.): 30kg
