Heat Conduction: Computer Interface
The unit consists of two parts: a multi section bar for linear heat conduction studies, and a metal disc for radial heat conduction studies.
- Linear Heat Conduction Unit.
- The unit has 3 sections which can be pressed tightly together. The first section is for heat input where a heater and three temperature sensors at 10 mm interval are installed. The center section has two temperature sensors at 20 mm interval. The last section is a heat sink section where cooling water and three temperature sensors at 10 mm interval are installed.
- The center section may be removed and replaced with a smaller heat conduction section or a different heat conduction material. Both replaced sections are without temperature sensors. Matching surfaces of the heat conduction section are accurately finished to minimize conduction resistance and a heat conducting compound may be applied to further reduce resistance. Thermal conductivity of an insulation material can be determined by inserting a thin insulating disc between two heat conduction surfaces.
- Radial Heat Conduction Unit.
- The unit consists of a brass disc heated at the center by a heater with cooling water circulating around the periphery. Six temperature sensors are placed along a radius.
- The metallic parts of both linear and radial heat conduction units are effectively insulated inside plastic casings.
- A service module provides power supply, heater control unit, and measuring instruments.
- The test unit requires outside water supply for cooling.
Instruction manual is also included.
TYPICAL EXPERIMENTS
- Heat conduction along a simple bar.
- Heat conduction along a composite bar.
- Effect of cross section area.
- Radial heat conduction.
- Effect of surface contact.
- Effect of insulation.

Air Flow and ThermodynamicsSubsonic Wind Tunnel: Upstream Fan
The wind tunnel is an open circuit upstream fan type, designed for studying the subsonic aerodynamics. It is to be used with optional accessories and models below.
An axial flow fan delivers air through a diffuser, aluminum tube flow straightener, three wire mesh screens and a high contraction ratio section to ensure uniform velocity across the transparent test section. The diffuser and contraction sections have a high quality internal finish to minimize the boundary effects. The fan impeller blades are of an aerofoil design cast aluminum to ensure maximum aerodynamic efficiency and minimum turbulence. The fan speed is adjustable by an inverter.
Four equally spaced static pressure taps are connected to a manifold to minimize effects from a model and air speed is indicated by an inclined manometer and a calibration graph. Models are mounted on two components load cell support with digital display for measurement of drag and lift. Model holder can be rotated to allow quick change on the angle of incidence, this angle is indicated on an angular scale.
The wind tunnel is mounted on a steel table on wheels.
