Product Description


Convectiveheat transfer is the transfer of heat between a surface and a fluid. Theprocesses of convective heat transfer are associated with the movements of the fluidthat is to say with convection. In the case of forced convection, thefluid is fed by a pump or fan onto the transfer surfaces, whereas in the caseof free convection, the flow occurs only under the effect of the densitydifferential of the heated fluid. The Convective heat transfer In Air Flowand its accessories allow studying the convective heat transfer with differentgeometries of the transfer surface. Typical models such as the tubebundle, the heated tube from the outside and the heated cylinder from theinside are observed. It is also possible to show the chimney effect insidea ventilation shaft during free convection. The measuring section is an airduct with fan, in which the model of heat exchanger can be fixed easily andquickly using quick couplers. The air passes in front of the model, warmsitself up and leaves by a ventilation shaft. In the air duct, aflow-friendly inlet member provides a homogeneous flow for conducting thetests. The volumetric flow rate is adjusted by a butterfly valve locatedat the fan outlet. To make it possible to observe the tests, the air ductis equipped with two windows. The model included in the bundle heat exchangerdelivery list includes two exchangeable tubular bundles of differentgeometries. An immersion heater, which can be placed anywhere in the tubebundle, simulates a heated tube. The convective heat transfer can thus bedetermined according to the position of the tube. Other models areavailable as accessories. A pitot tube and a pressure measuring device make itpossible to determine the speed distribution in front of and behind themodels. The heating power and the volumetric flow can beadjusted. The heating power and the temperatures of the air and the heaterare displayed numerically.
