Thermal Engineer Interview Questions and Answers

Explicit scheme calculates future values using current values while implicit scheme uses future values to calculate current values.

• Explicit scheme is faster but less accurate than implicit scheme.

• Implicit scheme is more stable and accurate but slower than explicit scheme.

• Explicit scheme is used for problems with short time steps while implicit scheme is used for problems with long time steps.

• Examples of explicit scheme include Forward Euler and Runge-Kutta methods while examp...read more

Heat treatment is a process used to alter the physical and sometimes chemical properties of a material through controlled heating and cooling.

• Heat treatment involves heating a material to a specific temperature, holding it at that temperature for a certain amount of time, and then cooling it at a controlled rate.

• The purpose of heat treatment is to improve the material's hardness, strength, toughness, ductility, or other properties.

• Common heat treatment processes include annea...read more

Thermal dynamics is the study of how heat energy moves and changes within a system.

• It involves the study of heat transfer, thermodynamics, and energy conversion.

• Thermal dynamics helps in understanding how heat flows from hot to cold regions.

• It is crucial in designing efficient cooling systems for electronics or engines.

• Thermal dynamics also plays a role in HVAC systems and renewable energy technologies.
