SBIR Phase I: Innovative Dense Gas Organic Rankine Cycle Engines

9860391 这个小企业创新研究第一阶段项目由Krispin技术公司提出。将探索新的概念，改善有机朗肯循环发动机（ORCEs）利用不寻常的流体动力学行为描述了一个相对较新的科学领域称为“稠密气体动力学。“ORCE目前正在制造和用于许多需要可靠、无人值守电源的远程地面应用。ORCE中的主要损失机制之一是由于涡轮机级中产生的冲击波。利用“稠密气体”工作流体来减弱或消除冲击可以潜在地减少这种损失。主要研究人员的初步结果表明，与传统ORCE工作流体相比，稠密气体工作流体的涡轮机效率有了非常显著的提高。拟定的第一阶段工作包括计算参数研究，以确定最佳涡轮机级设计。根据这些调查结果，第二阶段的工作将涉及制造和测试原型发动机，以确定实际性能的改进。 通过这项研究和开发，预计ORCE的潜在改进将产生一种高效的发电技术，这将是商业发电行业的重大突破，并可能对能源生产产生重大的积极经济和环境影响。

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.
