FACULTY UG & PG LABORATORY AUGMENTATION PLAN

 


Propulsion/Combustion

Bomb Calorimeter

Exact composition of practical fuels is often not known

Determination of heating value (HV) is important

Familiarize the students how to use Bomb calorimeter to determine HV

Measure the HV of a solid fuel (such as wax) and compare the value available in literature

Droplet Combustion

The combustion of a multicomponent fuel with higher volatility differential leads to the disruptive phenomena such as puffing and micro-explosion.

The fragmentation caused by micro-explosion and puffing plays an important role in accelerating spray atomization in the combustion chamber, which can be considered as an effective way of promoting efficient combustion.

Educational Gas Turbine Jet Engine

A complete laboratory-based Turbojet engine demonstration unit.

Provision for measurement of pressure and temperature at several locations of the engine as well as engine speed and thrust.

Flame Lift Off, Flame Light Back

Provides data for the construction of flame stability diagrams

Enables students to investigate methods of improving flame stability limits

Allows investigation of the relationship between flame speed and air – fuel ratio for a variety of slow burning gaseous fuels.
