THE RD WORK COMPRISES TWO WORK PACKAGES:
- DEVELOP OPTIMISED FLOW SEPARATORS TO OBTAIN ECONOMIC HIGH PERFORMANCE HEAT TRANFER ELEMENTS FOR HEAT RECOVERY DEVICES, ESPECIALLY AT ELEVATED TEMPERATURES (FLUE GAS TEMPERATURE UP TO 500 CELSIUS DEGREES)
- INVESTIGATE AFTER OPERATING TEMPERATURE LIMIT OF NAPHTALENE AND DIPHENYL STEEL THERMOSYPHON.
Development and investigation of flow separators to separate the counter current liquid and vapour flows in a closed 2-phase thermosyphon have been carried out. The goals to achieve are high heat transport capability and, at the same time, high effective thermal conductance. Two different separator designs, denominated perforated tube separator and crossover separator, have been extensively examined, and optimised designs have been developed.
