STTR Phase I: Optimized Nano-Porous Surfaces for Boiling Heat Transfer

小型企业技术转移研究(STTR)第一阶段项目旨在开发一种利用均匀的纳米多孔表面(NPS)的热交换器技术，该技术将显著提高沸腾过程的效率。NPS技术为小型到大型热力发电设施、发电厂和电子冷却硬件提供了相当大的沸腾换热能力。拟议的第一阶段研究的目标是：1)开发适用于锅炉的有效核动力源，2)证明核动力源技术相对于其他传统换热器技术的有效性，以及3)评估基于核动力源的供热锅炉的长期性能。将建造一个多管锅炉原型并进行工业部署测试。拟议项目的目标将通过生产在沸腾过程中产生更小和可控制的气泡尺寸的表面来实现。与传统的平坦表面和以前研究过的微孔表面涂层不同，NPS技术可以提供更好的长期耐用性、制造简单和低成本的手段，以实现更高的性能和更节能的热传递。这项技术的成功实施将在国内和国际能源市场上节省数百万美元。

The Small Business Technology Transfer Research (STTR) Phase I project aims at developing a heat exchanger technology utilizing a homogeneous nano-porous surface (NPS) that will significantly increase the efficiency of the boiling process. The NPS technology offers considerable enhancement in boiling heat transfer capabilities for small- to large-size heat generating facilities, power plants, and electronics cooling hardware. The goals of the proposed Phase I research are: 1) to develop an effective NPS for boiler applications, 2) to demonstrate the effectiveness of the NPS technology against other conventional heat exchanger technologies, and 3) to evaluate the long-term performance of the NPS based heat boiler. A prototype multi-tube boiler will be constructed and tested for industrial deployment.The objectives of the proposed project will be achieved by producing a surface that can generate smaller and controllable bubble sizes during boiling processes. Unlike traditional flat surfaces and previously investigated micro-porous surface coatings, the NPS technology can offer improved long-term durability, a simple-to-manufacture and low-cost means of achieving higher performance and more energy efficient heat transfer. Successful implementation of this technology will result in millions of dollars saved nationally and internationally in the energy market.
