FEASIBILITY STUDY OF NEW HEAT TRANSPORTATION SYSTEM WITH DRAG-REDUCING SURFACTANT ADDITIVES

要約

Utilizing drag-reducing fluid -water added with surfactant, the pumping power in thermal energy transportation can be reduced significantly. When surfactant is added to a installed system that uses water, the increased flow rate and deterioration of heat transfer can result in a drop in the temperature level and total heat to users. At the same time, the pump system must be modified due to the lowered pumping power. A simulation was conducted to predict the exergy and energy transportation efficiency. The minimum heat transfer reduction in order to maintain high exergy efficiency was discussed through the prediction.
