Summary
The three areas of investigation covered by the research program are the manufacturing, the heat transfer-fluid flow performance, and the theoretical basis for the performance of spirally fluted tubes. The results of this investigation show that (1) the estimated price of spirally fluted tubing in quantity is equivalent to the cost of present commercially available welded tubing and is considerably lower than that of drawn tubing, and (2) spirally fluted tubing exhibits heat transfer-fluid flow performance advantages over conventional tubing which should lead to tubing cost savings of a factor of two over welded tubing and more for drawn tubing. This implies a lower cost for heat exchange equipment, since a significant part of the cost of this equipment is the cost of the tubing and the remainder of the cost is dependent on the amount of tubing. The dependency is less than linear. Furthermore, a decrease in heat exchanger cost influences plant or system optimizations in the direction that leads to higher efficiencies in product, either in the utilization of raw material in the case of process plants or in the utilization of fuel in the production of power.
