Week 6 - CHT Analysis on a Graphics card

Objective: -

AIM Perform the Conjugated Heat Transfer Analysis on a model of Graphics card

1. Simulate by varying the velocity from 1m/s to 5m/s for at least 3 velocities and discuss the results.

2. Find out the maximum temperature and heat transfer coefficient attained by the processor.

3. Prove that the simulation has achieved convergence with appropriate image and plots.

4. Identify potential hotspots on the model

Introduction: -

Heat transfer is the flow of heat due to temperature differences and associated changes in temperature distribution. It refers to the exchange of momentum, mass and energy through conduction, convection and radiation.

CHT is the heat transfer due to heating and cooling of solid due to interaction between the solid and liquid as a strong coupling between the phases from convection, conduction and radiation.

Practical CHT problems are used to determine,

The maximum and minimum temperature various parts of the system, e.g.: combustion chamber, gas turbine, chemical vessel etc.

Temperature Response in time-dependent applications such as heating/cooling problem(For example, in the case of cooling a particular system such as engine cooling)

Overall heat transfer coefficient.
