This is a combined experimental and numerical study of a wall-driven tornado flame. The main objective of this project is to see how the rotational speed of the wall affects the flame’s properties, in particular the flame-length and maximum temperature, and whether these effects can be controlled. There are two parts to this project. First, a numerical study is conducted using a computational fluid dynamics software to see if a rotating cylindrical wall around a flame will indeed affect the flame properties. All simulations are set up and performed using the ANSYS Fluent package and different cases of varying rotational speed are evaluated. The results are then analyzed, focusing on the length and maximum temperature of the tornado flame. Using the simulation results, a corresponding physical experimental setup is then designed, which can be used to verify the numerical findings and facilitate future research.
