# Simulation Quiz 4

### Thermal Analysis of an Engine Cylinder

In a number of engineering applications, gaskets are used to ensure proper sealing. One such application of gaskets is an engine, When the engine is running, temperatures inside the engine body rise rapidly causing the gasket and the rest of the assembly to heat up, too. Here, we simulate a case where the inner surfaces of a are at elevated temperatures due to internal combustion happening inside.  We wish to find the temperature distribution over the head, gasket, and body.

1 / 10

In System B (“Cold Day”), what is the maximum temperature of the entire assembly?

2 / 10

In System B (“Cold Day”), what is the heat flow rate leaving the engine assembly (i.e. from outer surfaces of the assembly to the surrounding air)? [Hint: heat flowing out of the engine is equal to the reaction due to the Convection boundary condition applied on the outer surfaces.]

3 / 10

Which of the following are boundary conditions available in Ansys Mechanical? Select the three best options:

4 / 10

For the current mesh that is used for this analysis, what is the order of the elements used?

5 / 10

In System A (“Warm Day”), what is the maximum temperature of the Gasket part?

6 / 10

In System A (“Warm Day”), at what rate does heat flow from the ignited fuel into the engine assembly? [Hint: heat flowing into the engine is equal to the reaction due to the Convection boundary condition applied on the inner surfaces]

7 / 10

In System B (“Cold Day”), what is the maximum of the Gasket part?

8 / 10

When applying a Convection boundary condition, which Scoping Methods are available in Ansys Mechanical? Select the two best answers.

9 / 10

In System A (“Warm Day”), what is the minimum temperature of all of the bolts? Consider all the bolt heads, the shanks and the nuts.

10 / 10

In System A (“Warm Day”), where does the maximum temperature occur in the assembly?
