Digital Flow Rate Measurement System Design for Minichannel based on Cross Correlation Technique

Abstract

In this paper, a demonstration for an experimental study to measure mean fluid velocity in minichannels is presented. Fluid flow velocity was estimated by applying cross correlation technique on measured thermal fluctuation using two ultra-small thermistors in every channel. These experiments were conducted on two flow field plates (single serpentine and parallel Z-type arrangement) with dimensions (L*W*H= 75*70*3
