Malviya, Vihar, Mishra, Rakesh, Palmer, Edward and Majumdar, Bireswar (2007) CFD Based Analysis of the Effect of Multi-Hole Pressure Probe Geometry on Flow Field Interference. In: Fluid mechanics and Fluid Power. Birla Institute of Technology, pp. 113-122.

Multi-hole pressure probes are extensively used to characterise three dimensional flows in difficult
applications [1,2]. These probes provide sufficiently accurate information about flow velocity.
They have the advantages of being, usable with high temperature fluids, simple to fit have
practically no additional flow losses
In this paper the influence of the probe geometry on the flow field disruption has been reported.
The values and ranges of variations of the flow field parameters in the model have been assessed
on the basis of the numerically computed velocity and pressure fields around and inside the probe
[3]. For this probe interior details have been modelled fairly accurately.
The flow field has been predicted using computational fluid dynamics and the characteristics
linking the degree of interference with probe head shape have been presented. The conclusions
have been formulated taking complex flow metrology needs into account.
