Assignment 1

GUI of GT-suite:

GUI is divided in various functional regions like Tree Pane, Modelling Central Screen and various options for setting up the pre-processing of the model. Tree Pane is further classified into five different categories Flow, Mechanical, Thermal, References, Acoustics and General.

There are also five different sub categories for these variables as follows:

• Template: It's a parent of objects and parts which is used to model different components such as Engine, crankcase, vehicle, etc.
• Objects: It's a parent of parts and can be modified to change the properties of different objects at the same time.
• Parts: Various parts such as inlet valve, inlet port can be modelled here.
• Connections: connections that link various parts are modelled here and their dimensions are custumizable.
• References: These are non-graphical objects rather data, that needs to be fed to various parts, acting as a crux information.

Output Setup for Intercooler:

Simulating Charge Air Cooler in GT Power:

Given

• Diameter of cooler inlet and outlet pipe= 50 mm
• Length of the CAC= 1000 mm
• Inlet mass flow rate = 1200 kg/ h at 100 degC
• Outlet pressure 2 bar at 30 deg C

After loading the intercooler model from tutorials, the inlet mass flow rate, inlet air temperature, diameter of the CAC hasd been set according to the given values.

Finally the outlet pressure and temperature have also been setup

Processing:

In the time control module, the simulation has been setup to run for 30 seconds, also after reaching the steady state simulations stops the iterations for reduced processing time.

The simulation is processed in GT-Post:

Total Heat Transfer in the output: 3.41 kJ

The pressure drop across the CAC is found to be: 1.19e-5 bar.
