Computerized Steady State & Non Steady Heat Transfer
Product Code : EL-HAMTLE-10757
Computerized Steady State & Non Steady Heat Transfer (code EL-HAMTLE-10757) is a trainer for studying steady and transient heat conduction in cylindrical metal samples placed between an electrically heated heat source and a water-cooled heat sink. Each 40 mm diameter sample carries 12 type K thermocouples along its length, the 800 W heater holds the heating water at a set point within 20 to 85 °C, and temperatures, heating power and cooling water flow rate are shown digitally and sent to a PC via USB.

What Is the Computerized Steady State & Non Steady Heat Transfer Used For?
Heat conduction is the transport of heat between molecules driven by a temperature difference. In steady conduction the temperatures along a bar stay constant, and the gradient they form, together with the heat flow, gives the thermal conductivity of the metal; in transient conduction the temperatures change with both time and position. Students insert a copper, aluminium, brass, steel or stainless steel sample, set the heating water temperature and let the elevated tank feed cooling water at a steady rate, then record the 12 thermocouple readings once they settle. Changing the cooling water flow creates a temperature jump, and the PC plots how the temperature profile develops.
What to Specify When Ordering

Frequently Asked Questions
What is the difference between steady and transient heat conduction?
In steady conduction heat is supplied continuously and evenly, so temperatures stay constant; in transient conduction the temperature in the body changes with both position and time.
Which metal samples are supplied?
Samples are 40 mm in diameter: three are 450 mm long, in copper, aluminium and brass, and two are 300 mm long, in steel and stainless steel.
How is the temperature along the sample measured?
Each sample has 12 measuring points with type K thermocouples, designed to influence the temperature as little as possible so that the core temperature is recorded. Pt100 sensors measure the heating and cooling water.
How is a constant cooling water flow obtained?
An elevated tank of approx. 6 L feeds the water-cooled heat sink at a constant flow rate, and adjusting this flow produces a temperature jump for transient tests.
What can the software show?
Measured data are sent via USB to a PC, where the included software calculates thermal conductivity and displays the transient temperature distribution in the sample over time and place.
How large is the trainer?
It measures approx. 1200 × 800 × 1600 mm and weighs approx. 120 kg, and it runs on a 230 V or 120 V single-phase supply.
