Abstract

To keep the water temperature even throughout the bathtub and as close as possible to the initial temperature without wasting too much water, we establish a mathematical model of the temperature of the bathtub water in space and time to determine the best strategy the bather can adopt when bathing. On the basis of the model, we propose two water adding strategies. The first strategy is that the faucet keeps open, namely there is constant trickle of hot water added into the bathtub all the time. The second is that the bather turns on the faucet only when water is cooler. We use the heat conduction equation in strategy I. With Alternating Direction Implicit (ADI) Method, we get the numerical solution to the heat conduction equations. Then, we calculate the water consumption in strategy II with improved Genetic Algorithm. After comparing the consumption of water with the condition of stationary bath time, we discover that adding water intermittently can save more water.
