Abstract

In this study, structural problems of a hair dryer was analyzed by computational fluid dynamics analysis, and the structure of it was optimized by improving the impeller design. First, we measured the maximum velocity of a hair dryer for four different impeller speeds based on the KS standard (KS C 9209:2013). By analyzing the air flow profile inside the hair dryer using COMSOL Multiphysics, we confirmed that the pressure at the lower end of the impeller increased due to the stagnant flow at the lower end of the hair dryer. We solved this abnormal air flow by changing the height and angle of the impeller. We also verified the validity of the simulation by calculating the maximum air flow of a hair dryer and comparing it with that of the experiment. Consequently, we designed a hair dryer such that the maximum wind speed was improved by 34.4%-56.8%.

Keywords:

Hair dryer, KS standard, Computational fluid dynamics(CFD), Laminar flow, Maximum flow velocity
