9860391 This Small Business Innovation Research Phase I project proposed by Krispin Technologies Inc. will explore the novel concept of improving organic Rankine cycle engines (ORCEs) by exploiting unusual fluid dynamic behavior described by a relatively new area of science known as "dense gas dynamics." ORCEs are currently being manufactured and used for numerous remote terrestrial applications requiring reliable, unattended power. One of the major loss mechanisms in ORCEs is due to shock waves generated in the turbine stage. Utilizing a "dense gas" working fluid to weaken or eliminate the shocks can potentially reduce such losses. Preliminary results by the Principal Investigator show very significant improvements in turbine efficiencies for dense gas working fluids over conventional ORCE working fluids. The proposed Phase I work consists of a computational parametric study to determine the optimal turbine stage design. Based on these findings, phase II work would then involve building and testing a prototype engine to determine actual performance improvements. The potential improvements to ORCEs anticipated through this research and development will result in an efficient power generation technology that would represent a major breakthrough in the commercial turbomachinery industry and could have significant, positive economic and environmental impacts in energy production.

9860391这个由Krispin Technologies Inc.提出的小型企业创新研究第一阶段项目将探索通过利用一个相对较新的科学领域“稠密气体动力学”所描述的不寻常的流体动力学行为来改进有机朗肯循环发动机(ORCE)的新概念。ORCE目前正在制造，并用于许多需要可靠的无人值守电力的远程地面应用。ORCEs的主要损失机制之一是涡轮级产生的激波。利用“稠密气体”工质来减弱或消除冲击波，可能会减少这样的损失。首席调查员的初步结果表明，与传统的Orce工质相比，稠密气体工质的涡轮效率有了非常显著的提高。拟议的第一阶段工作包括确定最佳涡轮级设计的计算参数研究。根据这些发现，第二阶段的工作将涉及建立和测试原型发动机，以确定实际的性能改进。通过这项研究和开发预期的ORCE的潜在改进将产生一种高效的发电技术，这将是商业透平机械行业的重大突破，并可能对能源生产产生重大的积极经济和环境影响。
