Invited review article: Unsteady and pulsating pressure and temperature: a review of experimental techniques.
TLDR
This paper reviews the current state of the art in sensors and measurement techniques for the characterization of pressure and temperature in unsteady and pulsating flows including an analysis of the advantages and limitations of each technique.Abstract:
Unsteady flow of liquids and gasses are important in many scientific, engineering, and biological contexts. Measurement of the characteristics of unsteady and pulsating flows is more difficult than that of static flows. Time constants of the sensors must be understood, sampling rates must satisfy basic signal processing criteria and synchronization of the measurements with the flow may be necessary. Because of development of more advanced measurement devices, there has recently been a growing interest in unsteady and pulsating flow measurements and the number of papers in this field has increased in recent years. This paper reviews the current state of the art in sensors and measurement techniques for the characterization of pressure and temperature in unsteady and pulsating flows including an analysis of the advantages and limitations of each technique.read more

Springer Handbook of Experimental Fluid Mechanics
TL;DR: A central organizing theme of this handbook is that 'experimental fluid mechanics" can be understood as a parallel activity to that described above, in which basic expressions are combined to analyze a given problem and to derive new information and insight from the resulting mathematical steps of the analysis.
