Objective: To study the function theory of an anesthesia vaporizer and measure the geometry configuration. Methods: The effect of dilution air temperature on evaporation process in anesthesia vaporizer was simulated by using CFD method. According to stochastic particle tracking in turbulent flow, for the droplet of anaesthesia drug, the moving track of droplet in evaporation space was traced. By this way, the results of the concentration distribution of anaesthesia drug volatilization process and mixing process with gas were ascertained. Results: Numerical simulation results showed that the influence of dilution air temperature on anesthesia drug volatilization and mixing process between anesthesia drug vapor and dilution air was clear. Conclusion: Increasing air temperature suitably can improve the mixing process and the stability of anesthesia drug volatilization concentration is also improved.
