The various modules available in GT-SUITE:

COOL3D:

• COOL3D is a tool that can be used to build 3D models of underhood thermal management flow systems that can be discretized and made into model files for use with GT-SUITE. It provides the ability to build the model in a 3D environment so that the full details of the model can be included. It also includes sophisticated discretization logic that is able to transform the 3D model into a model file that is compatible with the GT-SUITE software. COOL3D can be used to build any flow system that contains only blockages, fans, heat additions, and heat exchangers

GT-ISE:

• It is the main interface where models are built and simulations are launched. It is an environment where all the elements are brought up to the map and connected together linking the entire model. It creates the model in sequential order step by step like engine cylinder, engine crankshaft, combustion, Valve train, etc.

GEM 3D:

• GEM3D is a tool that can be used to build 3D models of flow, thermal, and mechanical systems that can be discretized and made into model files for use with GT-SUITE. It provides the ability to build the model in a 3D environment so that the full details of the model can be included. It also includes sophisticated discretization logic that is able to transform the 3D model into a model file that is compatible with the GT-SUITE software. GEM3D can be used to build any system that contains components like pipes, mufflers, manifolds, air boxes, heat exchangers, underhood, cabin, batteries, crankshafts, etc.

GT-POST:

• GT-POST is a powerful data analysis tool used to plot, view, and manipulate data generated either by a GT-SUITE simulation or by an external source. It offers a more efficient data analysis solution than standard spreadsheet software. By employing data pointers, the results viewed in GT-POST are updated automatically and immediately when a model is changed and a simulation is a rerun. Also, GT-POST lends itself nicely to the development of portable, user-defined templates that control how results are presented.

VT-DESIGN:

• VTDESIGN is a stand-alone, interactive cam/valvetrain/spring design tool supplied with GT-SUITE that may be used as a preprocessor to GT-SUITE. VTDESIGN is composed of three main features including the Cam Design feature, the Valvetrain Design feature, and the Spring Design feature. These three features can be accessed at any time by clicking on the separate tabs in the lower left-hand corner of the project window titled "CamDesign", "Valvetrain", and "SpringDesign".

GT-SpaceClaim:

• GT-SpaceClaim is a tool that can be used to import CAD geometry of various formats, extract volumes and export them for discretization in GEM3D. Building and exporting 3D models of flow systems is also possible. These basic shapes can be created with GT-SpaceClaim. These shapes are similar to the ones that can be created in GEM3D and can be combined to form complex geometry.

2.  Locate the following settings:

• Time control flag

Time control flags are of two types, continuous and periodic used according to case setup. For Engine applications, the Time control flag is periodic, and for other applications continuous. In max. simulation duration we define the time for which the setup will run to get a converged solution.

• Time step and solution control

The Time step defines the duration of the simulation result to converge. we can control time step and solution with the option of automatic shut off when steady state, with one option when the solution converges it will automatically stop running setup. 

• Integrator/Solver type

There is a lot of solver option like the Runga Kutta method in the below Run Setup option.

• Run setup

• Advanced setup

• Plot setup

• Output setup

4. Problem:

    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

• Set the simulation time to 1 sec.

• Run the simulation

• Calculate the Average heat transfer at the Charge air cooler (CAC)
• Calculate pressure drop across CAC

• Average heat transfer at the Charge air cooler (CAC) = 8.440299 kW
• pressure drop across CAC = 2.141832 bar
