The study of the physics of a round jet flow is a fundamental part of fluid mechanics’ research. The analysis of the flow structure after mixing provides scope for understanding phenomena about the physics of flows and vortices. Thermal anemometry as a sampling method gives a range of options for experimental data acquisition for flow calculation. The hot-wire continuoustemperature thermal anemometry method (HWA-CTA) gives results with little deviation that can be interpreted for investigating a flow. By interpreting the results, we can through the calculation of turbulent intensity and spectraStrouhal number diagrams, see the presence of a potential core of the jet (0.75*D) and the increase of turbulence and dunes beyond it. In this thesis, a new jet flow arrangement in the lab is studied using a hot wire thermal anemometer. The objective is to study the flow of the jet flow ldownstream of the nozzle.
