摘要

In order to create a comfortable and cost-effective hot bath condition for everyone, we invent a bathroom environment to simulate the process of people taking a bath. Then, What are a hot bath made of? There must be a bath crock, a tired man who is eager to clean himself. In this way, we got the two key elements of a bath. Then we can find a really good bath strategy to achieve a comfortable bath by coordinating the two factors. We put aside the man who wants to take a bath. And we just consider the heat transfer inside the bathtub which filled with hot water in a constant temperature bathroom. We divided the water in the bathtub into many small water cube. Then we simulate the change of the temperature of every water cube from outside to inside. According to those changeable water cubes, we build a temperature field of the hot water in the bathtub in time and space.
