The melting thermal performances of MEPCM (microencapsulated phase-change material) composite plates were investigated experimentally. The effects of MEPCM particle fraction in the plate, PCM core fraction in a single MEPCM particle, volume fraction of high thermal conductivity additives on the...

A three-dimensional DDF-MRT-LBE (double distribution function multi-relaxation-time lattice Boltzmann equation) is presented to study the flow and heat transfer in dimple heat exchangers. Results are obtained for periodically fully-developed laminar flow in parallel-plate channels with spherical...

To improve heat transfer performance and reduce erosion of economizers in coal-fired power plants, firstly the heat transfer and erosion characteristics is numerically studied for the single H-type finned oval tube with enhanced heat transfer structures including bleeding dimples, longitudinal...

The experimental system for the transcritical CO2 residential air-conditioning with an internal heat exchanger was built. The effects of working conditions on system performance were experimentally studied. Based on the experimental dada, the second law analysis on the transcritical CO2 system...
