AP Dynamic Inc.在扭转振动、**管道应力、脉动和侵蚀缓解以及机械设计领域提供高价值的工程服务和分析。目前的挑战之一是由于蒸汽流动中**存在水滴，导致一次过热回收蒸汽发生器(OTSG)管道的**侵蚀。为了调查蒸汽喷射在管道内造成的侵蚀速度，AP Dynamic和**卡尔加里大学建立了合作关系，设计、制造、优化和测试**模拟集成传感器的蒸汽喷射系统的**装置。该项目是之前举办的**NSERC DG和艾伯塔省校园小型企业参与计划的延伸，目的是使用各种测试券和不同质量的蒸汽和污染物，进一步调查蒸汽管道中的腐蚀率**。我们将**研究在不同的蒸汽喷流速度、攻角和湿蒸汽量下影响管道内表面冲蚀率的参数。我们还将根据**实验结果预测侵蚀速度。腐蚀率的预测对于OTSGs防止灾难性故障和**优化蒸汽辅助重力排水(SAGD)提取重烃的过程至关重要。研究的**结果将使HQP的培训成为可能，并为AP Dynamic在**评估蒸汽锅炉的冲刷腐蚀故障方面提供竞争优势。

AP Dynamics Inc. provides high-value engineering services and analysis in the fields of torsional vibrations,**piping stress, pulsation and erosion mitigation, and mechanical design. One of the current challenges is the**erosion in Once Through Heat Recovery Steam Generators (OTSGs) piping due to water droplets existing in**the flow of steam. To investigate the erosion rate caused by the steam jet within the pipes, AP Dynamics and**the University of Calgary have formed a collaborative relationship to design, manufacture, optimize, and test a**setup to mimic the steam jet system with integrated sensors. This project is the extension of previously held**NSERC DG and Campus Alberta Small Business Engagement Program to further investigate the erosion rates**in the steam pipes using various test coupons and different quality of steam and contaminants. We will**investigate the parameters influencing the erosion rate of the internal surface of the pipes at different steam jet**velocites, attack angles, and amounts of wet steam. We will also predict the erosion rate based on the**experimental results. The prediction of erosion rate is critical for OTSGs to prevent catastrophic failures and**optimize the Steam Assisted Gravity Drainage (SAGD) processes for extraction of heavy hydrocarbons. The**outcomes of the research will enable training of HQP and provide a competitive edge for AP Dynamics for**evaluating erosion-corrosion failures of steam boilers.
