Molecular Dynamics Simulation of the Heat Transfer Coefficient at the Interface between CNTs and Water in the Carbon Nano-Tubes Micro-channel Cooler

In this paper, a molecular dynamics simulation method is carried out to simulate the coefficient of heat transfer at the interface between CNTs and water in the carbon nano-tubes micro-channel cooler. The influences of temperature and the boundary velocity on the CNTs heat transfer coefficient are considered. It is shown that: with the temperature increasing, the heat transfer coefficient between the CNTs and water molecules is increasing, but when the temperature is closing to the boiling point of water, the heat transfer coefficient is decreasing. When the temperature is closing to the boiling point of water, a large amount of bubble will appear at the interface between CNTs and Water which prevents the water from taking heat away.
