Abstract

To analyze the temperature field distribution of three-dimensional bathtub, the finite element method is applied. This is one of the very important parts of dealing the problem and establishing an appropriate model. Galerkin method of weighted residuals is used to obtain the variational equation of the three-dimensional temperature field. The bath water is discredited by using tetrahedral element and according to the third-class boundary conditions as well as the face very coordinates points transform law together with the initial conditions, all the temperature field are carefully simulated on ANSYS software. For transient temperature field, we use finite difference method to discredited the time-step and successfully solve the transient temperature field governing equation by replacing differentiation with difference method. The problem is surely a complicated one, so it is better to start with factors like air and water temperature, the shape and material of bathtub and location of faucet and overflow drain. Make reasonable assumption of some needed parameters at the same time. The model we build follows a process from easy to complicated. A model without human is built to examine the cooling and adding hot water process. By using finite element method, temperature distribution of the bathtub is cleared of the charge of time. Heat exchange and the influence of energy, momentum and flow between cold and hot water are also taken into account.
