Improvised Typhoon Maker: A Vortex Flow to Easily Demonstrate Typhoon and Vortex to Senior High School STEM Students

Abstract

The improvised typhoon maker is an apparatus needed to stir fluids continuously which are made up of economical materials. A vortex is a deformation of the free surface and the underlying flow were linked to each other. The purpose of this experiment is to capture a visually appealing and eye satisfying image of vortex which is comparable to a typhoon where we can demonstrate its formation and point out its strongest and weakest points, thus the students will gain knowledge about the signal number of a typhoon, and be able to familiarize the risks it bring. Results revealed that it can be used to demonstrate and discuss the formation of a typhoon, tornado and the like. It can help to discuss the parts of a typhoon, its strongest and weakest point and the corresponding signal number that can be helpful in understanding the risks it bring.
