Effect of Concentration on R134a/Al2O3 Nanolubricant Mixture Boiling on a Reentrant Cavity Surface with Extensive Measurement and Analysis Details

September 25, 2013

Author(s)

Mark A. Kedzierski

This paper quantifies the influence of Al2O3 nanoparticles on the pool boiling performance of R134a/polyolester mixtures on a Turbo-BII-HP boiling surface. Nanolubricants with 10 nm diameter Al2O3 nanoparticles of various volume fractions (1.6 %, 2.3 %

Horizontal Convective Boiling of R134a, R1234yf/R134a, and R1234ze(E) within a Micro-Fin Tube with Extensive Measurement and Analysis Details

August 15, 2013

Author(s)

Mark A. Kedzierski, Ki-Jung Park

This report presents local convective boiling measurements in a micro-fin tube for R134a and two low global warming potential (GWP ) refrigerants: R1234yf/ R134a, 56/44 % mass and R1234ze(E). Water heating either in counterflow or in parallel flow with the

Evaluating Feedback Systems for Residential Building Energy Monitoring
