A thorough understanding of the basic modes of Heat Transfer is a fundamental requirement for most courses in Science and Engineering. The P.A.Hilton Ltd Heat Transfer range is designed to teach all the fundamental principles of Heat Transfer and Thermodynamics as well as units for more advanced studies.
Many of the ranges have a common instrumentation and service unit with a series of optional add-on modules available, designed for specific applications. This modular approach gives maximum flexibility to educational establishments to align their laboratory equipment to curriculum requirements and budgets.
Data Acquisition Upgrades are available for the vast majority of units within the Heat Transfer range, allowing the key experimental parameters to be captured using the Universal Data Acquisition software.
Recycling can be used in many engineering applications and is important when applied to thermodynamic processes as it can result in reduced energy requirements.
Vapour may condense onto a cooled surface in two distinct modes known as filmwise and dropwise. For the same temperature difference between the vapour and the surface, dropwise condensation is several more times effective than filmwise. However it involves special surface finishes or treatment in order to maintain dropwise condensation and for this reason, though desirable, it seldom occurs in real plant operation.
A small water to air heat exchanger, illustrating the use of extended surfaces (fins) as a means of improving the heat transfer to gases(in this case air). A fan, powered from the H102 unit allows air to be heated by hot water from the H102 unit.
The Hilton H112 Heat Transfer Service Unit comprises a control, instrumentation and power supply console into which are connected a wide variety of optional experimental and demonstrational modules. The range of optional modules include the three fundamental modes of heat transfer and a wide range of additional experiments in thermodynamics and thermodynamic properties of materials. Data Acquisition of the modules is also available. A number of the key optional modules are shown below.
A small-scale accessory that allows experimental investigation of linear heat conduction and the measurement of the thermal conductivity of various solid conductors and insulators. An insulated, 25mm diameter brass heated section and cooling section that may be either clamped together, or assembled with one of four insulated intermediate sections or test specimens between the interfaces.
