The figure below shows the base of an electric kettle. Suppose a heat flux condition is defined through the| serpentine heating element embedded at the bottom of the kettle base. Except for the imprinted heating element face, all other faces of the kettle base are subjected to convective heat transfer with a bulk air temperature of 50 °C and a film coefficient of 85 W/m²°C. The heating element is made of structural steel with thermal conductivity of 60.5 W/mK, density of 7850 kg/m³, and specific heat of 434 J/kgK. The electric kettle base has a thickness of 20+X , X=2 " Similar to task 1, here, you must examine the performance of the base in three cases where the material (except the heating element) is changed. For each case, you must choose and assign a specific material member from the material families listed in the table and find the required properties from a handbook/software. You must discuss the details of how you found the properties in your report citing the references used. Case 1 2 3 Material Family Silver Copper Aluminium Specific Material Thermal Conductivity, k Density, p Specific Heat, c ? ? ? ? ? ? ? ? ? ? You should examine the temperature distribution and thermal response the following scenarios: (1) Study the steady-state thermal response of the kettle base if a constant heat flux of 800 W/m2°C is applied through the heating element. (2) Suppose the heating element is cycled ON and OFF with a period of 60 s (30 s ON time followed by 30 s OFF time). When ON, the heat flux is of magnitude 1000 W/m²°C. Study the transient thermal response of the kettle base for a duration of 180 s using the steady-state solution as the initial condition. Note: All dimensions in the below figure are in centimetres. Imprinted Heating Element Face: Kindly take note that the heating element should be defined as a plate and treated as an Imprinted Face in the Ansys settings. This implies that Ansys will treat the heating element's thickness as equivalent to the kettle base's thickness to carry out its calculations. If, for any reason, you are unable to enable this option, you can create the heating element in three dimensions, import it into Ansys, and establish the contact surfaces between th heating element and the base plate during the simulation. Isometric view of the two sides of the kettle base Heating element is shown as an imprinted face on the bottom of the kettle base.
