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.
