H112S Boiling Heat Transfer

H112S Boiling Heat Transfer

A bench top accessory designed to allow students to experimentally investigate convective, nucleate and film boiling. The unit consists of a high strength clear glass cylinder with instrumented electric heater element immersed in a volatile solvent that boils at low pressure.

An integral water cooled condenser coil allows the chamber pressure to be controlled over a wide range of negative and positive pressures depending upon the local water supply. A digital wattmeter allows students to determine the heat transfer from the heated element and this together with instrumentation on the H112 enables all relevant parameters to be recorded. An integral control con sole provides heater power control and high temperature/pressure safety cut outs. The chamber is also fitted with a safety valve.

Requires the H112 Heat Transfer Service Unit for operation.

  • Visual demonstration of convective, nucleate and film boiling.
  • Study of the heat flux and surface heat transfer coefficient at constant temperature.
  • Investigation of the effect of pressure on critical heat flux.
  • Study of filmwise condensation and condenser overall heat transfer coefficient.
  • Investigation of the pressure- temperature relationship of a pure substance, and the effect of  air in a condenser.
  • Demonstration of:
  1. Liquid carry over or priming in boilers.
  2. Law of partial pressures
