Digital Flow Rate Measurement System Design for Minichannel based on Cross Correlation Technique [PDF]
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 ...

Abstract The Kigali Amendment's mandate to phase down high‐GWP refrigerants highlights the urgent need for sustainable alternatives in cold climate heat pumps, which are critical for delivering efficient heating in severely cold regions. This study evaluates ultralow‐GWP refrigerants—R‐290, R‐152a, R‐161, R‐1234yf, and R‐1234ze(E)—for application in a ...

ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling
