Week 1 : Exploring the GUI of GT-POWER

Aim : Explore the GUI of GT-Suite and run the intercooler setup.

GT SUITE:

GT-SUITE is the industry-leading simulation tool with capabilities and libraries aimed at a wide variety of applications and industries. It offers engineers functionalities ranging from fast concept design to detailed system or sub-system/component analyses, design optimization, and root cause investigation.

The foundation of GT-SUITE is a versatile multi-physics platform for constructing models of general systems based on many underlying fundamental libraries:

• Flow library (any fluid, gas or liquid or mixture)
• Acoustics library (both non-linear and linear)
• Thermal library (all types of heat transfer)
• Mechanical library (kinematics, multi-body dynamics, frequency domain)
• Electric and Electromagnetic library (circuits, electromechanical devices)
• Chemistry library (chemical kinetics)
• Controls library (signal processing)
• Built-in 3D CFD and 3D FE (thermal and structural)

 

Different modules available in GT SUITE are:

GT-AUTOLION : GT-AutoLion is the industry-leading lithium-ion battery simulation software used by cell designers and OEMs to predict performance, degradation, and safety for any Lithium-ion cell. It predictively models the electrochemical processes within Lithium-ion cells using a fast and reliable, electrochemical, physics-based approach.

GT-SUITE-RT: GT-SUITE-RT is supplied as a Simulink S-function, and the GT models are easily integrated into Simulink control system models for desktop simulation.

GT-TAITHERM: GT-TAITherm is a thermal and infrared signature modeling tool solving 3D conduction, convection and multi-bounce radiation.

GT-CONVERGE: GT-CONVERGE is a 3D CFD module which complements GT-SUITE and advances your plant and system level simulations. Importantly, it empowers non 3D-CFD experts, through features like autonomous meshing and dedicated easy-to-use simulation setup.

Intercooler Problem:

Problem Statement:

 

 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

 

Objectives:

Calculate the Average heat transfer at Charge air cooler (CAC)

Calculate pressure drop across CAC

 

Procedure:

Setting the Diameter of cooler inlet and cooler outlet pipes:

Set the diameter of cooler  inlet and cooler outlet pipe as 50mm

To change the diameter of i Flow > Components > PipeRound > cooler

 

Setting the length of CAC:

Change the length of length to 1000mm

Setting inlet and outlet conditions:

Inlet mass flow rate = 1200 kg/ h at 100 degC

Outlet pressure 2 bar at 30 deg C

 

Inlet:

 

Outlet:

 

After setting up the values Run the setup:

 

Results:

Average heat transfer of CAC cooler: 6.29 KW

 

Pressure drop across CAC: 0.083 bar

 

 

Conclusion:

• Intercooler simulation is done. The Heat transfer and Pressure drops are calculate
