Heat transfer laboratory

 

 

The Heat and mass transfer laboratory is used to demonstrate different processes and phenomena relating to heat and mass transfer. In the following courses, students learn to measure, calculate, and evaluate heat flows in apparatus.

  • Placement in heat and mass transfer (bachelor’s degree)
  • Fluid mechanics I (bachelor’s degree)

The Heat and mass transfer laboratory has the following facilities for demonstration purposes and application-oriented research with third party-funded projects and industrial companies.

  • Heat exchanger experimental area
    Tube bundle heat exchangers, double tube heat exchangers, plate heat exchangers, and cross-flow heat exchangers with plain or finned tubes can be investigated and compared. The measured temperatures, pressures, and mass flows are visualized on the PC using LABVIEW. Specially developed programs mean that the measured transfer capacity of the heat exchanger can be compared with the theoretically expected value according to the equations of the VDI Heat Atlas.
  • Waste gas heat exchanger
    The test rig makes it possible to determine the heat transfer coefficient of structured tubes when used in waste gas heat exchangers.
  • Mass transfer at the trickle film
    The mass transfer from a gaseous to a liquid phase is investigated on a trickle film column. Among other things, Sherwood, Reynolds, Schmidt, and Graetz numbers have to be determined to investigate the influence of mass flow and column height on mass transfer.
  • Heat transfer on a cylinder with a flow around it
    The analogy between heat and mass transfer is used to determine the local heat transfer coefficient along the circumference of a cylinder with a transverse flow.
  • Condensation
    Film and droplet condensation at different cooling water mass flows
  • Boiling
    Recording of the boiling characteristic curve in the area of nucleate and film boiling of water at wall temperatures up to approx. 250°C and of refrigerant at different pressures and temperatures.
  • Steady-state heat conduction in liquids
    Determination of the thermal conductivity of liquids
  • Steady-state and transient heat conduction in solids
    Determination of the heat and thermal conductivity of solids and the contact resistance of different surfaces
  • Flow lines
    Visualization of the flow around pipes and pipe bundles
  • Flow boiling
    Investigation of the multiphase flow during flow boiling
  • Heat transfer with laminar flow
    Investigation of the heat transfer in laminar flow
  • Diffusion
    Determination of the diffusion coefficient of a hydrocarbon vapour in air
  • Pipe flow demonstration plant
  • Mobile fluid mechanics laboratory
    Test rig for the demonstration of various fluid mechanics phenomena
  • Demonstration heat exchangers and exhibits

The Heat and mass transfer laboratory contains equipment that is used for final theses and application-oriented research with third party-funded projects or cooperation with industrial companies.
