文摘
- •
A numerical model is proposed for efficient transient simulation of heat pipes.
- •
Lumped vapor assumption and LBM solution significantly improve the simulation efficiency.
- •
The model accurately predicts detailed profiles of temperature, pressure and velocity.
- •
Optimized version is over 50 times faster than corresponding complete vapor model.
