TRAY DRIER

Tray Drier has been designed for student laboratory training programmes

in unit operations. The unit resembles the most commonly used industrial

method of drying solids in bulk where hot air stream is passed over fixed traysof wet material. Students will able to vary the operating conditions and collect

data to demonstrate both the theoretical and practical aspects of industrial

drying practice.

HEAT EXCHANGER TRAINING APPARATUS

This Heat Exchanger Training Apparatus has been designed to allowstudents to get Familiarised with different kinds of heat exchangers and to

collect the necessary experimental data for the calculation of heat loss, heat

transfer coefficient, log mean temperature difference, etc. Student will also be

able to study the effect of flow rate on the heat transfer rate. Later, students may

use this knowledge for designing complex industrial heat exchangers.

DOMESTIC REFRIGERATION UNIT

The Domestic Refrigeration Unitsystem demonstrates the operation of a

compression refrigeration unit. A closed, insulated chamber is cooled using a

refrigeration circuit comprising a compressor, condenser, evaporator andcapillary tube. A special feature is the ability to enlarge the heat exchange area

of the condenser by switching in a 2nd stage. It is possible to use the unit to

simulate faults.

HYDRAULIC BENCH

The hydraulic bench allows to carry out a large number of flow-relatedexperiments. To ensure a safe stand of the experimental set-ups, the work space

is provided with a stepped edge. The first part of the work space is in form of a

flow channel. Therefore, experiments with weirs are possible. The collecting

tank is used to measure the flow rate. Two different measuring ranges are

realised with a stepped tank. The work space including the measuring tank and

supply tank are made of reinforced fibreglass. Piping is made of PVC. The

components are corrosion-free, shock-resistant difficult to deform. The supply

tank includes a pump. The bench is independent from a water supply because ofthe closed water circuit.

FREE & FORCED CONVECTION APPARATUS

The system is developed for the demonstration of natural and forced

convection phenomena. A convection chamber is fitted with different heated

surfaces to determine its heat convection coefficients.

UNSTEADY STATE HEAT TRANSFER

The equipment is designed for students to run experiments on unsteady

state heat transfer. The unit is supplied with a heated water bath and a set of

solid shapes with built-in temperature sensors to monitor the temperature at the

centre of the shape.

FILM AND DROPWISE CONDENSATION UNIT

This Film and Dropwise Condensation Unit has been specially developed

for use in students teaching and demonstration purposes. It will enable students

to visually observe the process of heat transfer during condensation, as well as

gather experimental data for a better theoretical understanding. The unit is a self

contained bench top unit, with an integrated steam generator and air extraction

system. The main components in the unit are the specially designed condensers

for the observation of both filmwise and dropwise condensation.

LINEAR & RADIAL HEAT CONDUCTION APPARATUS

The apparatus is designed for students to study the principles of

conductive heat transfer in solids. A linear and a radial module is individually

used to verify the heat conduction theory.

COOLING TOWER DEMONSTRATOR

Cooling towers are a common type of heat exchanger used in the industry

where warm water is sprayed down while air flows up the column for heat

transfer. This apparatus clearly demonstrates the working principles of a cooling

tower.

MARCET BOILER

This Marcet Boiler is a bench top unit designed to demonstrate the

thermodynamic basic principal of boiling phenomenon. Students will be able to

study the fundamental pressure-temperature relationship of saturated steam inequilibrium with water.

RADIATION HEAT TRANSFER UNIT

The bench scale apparatus is designed for students to investigate the

fundamental aspects of heat transfer by radiation. Various radiation heat transfer

theorems are verified within the experiments.

PERFECT GAS EXPANSION UNIT

The equipment for this laboratory is located in the pilot-plant area of

Dupuis Hall. It consists of two interconnect rigid vessels. One vessel is

equipped for operation under pressure and the second is under vacuum. Anelectrical air pump and tappings are mounted on top of the vessels which enable

the vessels to be pressurized or evacuated as necessary. There is a pressure

sensor connected to each vessel and a temperature sensor is located within each

vessel, allowing continuous monitoring of the air properties contained within

the vessels.

DEAD-WEIGHT PISTON GAUGE

Using the HM 150.02 accessory set, the principle of operation of a spring

tube manometer and the possible methods of calibration can be conveyed to the

student. For the direct production of the calibration pressure, a pressurising

piston of precisely defined diameter in an oil cylinder is loaded with weights.

The pressures corresponding to the weights are then read off on the manometer

scale. The scale is made of transparent material, in this way the spring

mechanism is fully visible.

JOULE-THOMSON COEFFICIENT APPARATUS

Joule-Thomson apparatus is a demonstration and practice unit for

determining Joule-Thomson coefficient. With this, students are able to

comprehend basic concepts of real and ideal gas, internal energy, Gay-Lussactheory, throttling process, Vander Waals equation, Vander Waals force, inverse

Joule-Thomson effect, and inversion temperature. Joule-Thomson effect finds

its applications in liquefaction of gases, production of dry ice and in

petrochemical industry.

INSTANTANEOUS ELECTRIC BOILER FOR STEAM

This electric and automatic steam generator is fitted with two separate

sets of heating elements for single or double operation. The water can be

directly connected to the mains and the water calculation is ensured by a pump

rated at 0.55 KW.
