In this work the authors report on a CFD simulation of a pipe flow model. Fluid mechanics are here combined with heat transfer phenomena. To create a mathematical model of a pulsed hot wire system i.e., the thermo-fluidic impulse response of a pulsed hot wire, a simulation model is going to be analyzed which describes the impulse response according to the physics from thermodynamics.

The thermo-fluidic impulse response is characterized by heat transfer parameters. For several fluids and for different flow velocities these heat transfer parameters are investigated. Moreover, thermal Time-of-Flight (TOF) analysis for different fluids (oil and water) is accomplished. The basic concept is to measure a flow velocity by mainly convective heat transfer applying the thermal TOF method.
