Image for Laser diagnostics in reactive flows: Fluorescence & hybrid rotational coherent anti-Stokes Raman spectroscopy (HRCARS)

This talk is a part of two consecutive talks. The first talk will start at 13:00. Pizzas will be ready at 12:30.

Abstract:

Laser diagnostics have been a staple for experimental combustion research as a modern tool to evaluate high temperature reacting flow environments and to contribute to the fundamental knowledge needed for improving our current combustion systems in a non-intrusive way. This talk is divided into 2 parts, the first part uses OH planar laser induced fluorescence (PLIF) and two-photon CO PLIF to study CO emissions from an impinging plate. The second part introduces short-pulse hybrid femto-second/pico-second rotational coherent anti-Stokes Raman spectroscopy (HRCARS) to measure temperature. In future work, 1D HRCARS will be used in a novel experimental facility to measure the spatially-resolved transient boundary layer development at a single-wall surface.

Bio:

Dr. David Escofet-Martin is a postdoctoral research associate in the Institute for Multiscale Thermofluids (IMT) with a focus on laser diagnostics and light-matter interaction for gas phase environments. He graduated from the Escola Tècnica Superior d’Enginyeria Industrial i Aeronàutica de Terrassa (ETSEIAT) of the Universitat Politècnica de Catalunya (Spain), obtaining the degree of Mechanical Engineer in 2012. He earned a Ph. D in laser diagnostics for combustion in University of California Irvine in 2017.
