Zur Homepage

Dr. Christopher Abram

Core interest: development of advanced laser measurement techniques for reacting and non-reacting fluid flows, with the goal of improving our physical understanding in topics such as turbulent combustion, heat transfer, geophysical/astrophysical flows, fire research, bioimaging, multiple fields of automotive and aerospace engineering… The focus is on multi-dimensional simultaneous measurements of scalars (especially temperature) and velocity to probe complex flow interactions.

Thermographic phosphor particles can be used as a flow tracer in liquids and gases. The infinite variety of phosphors, in terms of composition (doped insulator, semiconductor, organic-inorganic hybrid…) and morphology (size, shape…), and the nature of the laser-particle interaction itself, means these sensor materials offer broad perspectives in developing new capabilities for flow measurements.
