## Coursera课程:化工工程师的管道/管线尺寸优化 本课程专为化工领域工程师设计,旨在深入讲解管道尺寸优化的核心原则与实践。在流量设计中,管道尺寸的计算至关重要。过小的管道尺寸虽然能降低初期资本成本,却可能因流速过高而导致一系列问题,如腐蚀、冲蚀、以及更容易发生的水锤效应,从而缩短设备寿命,增加维护成本。 本课程由一位经验丰富的油气行业工艺工程师讲授,面向本科生和研究生。内容涵盖了: * **流体流动基础:** 讲解剪切应力、流体流动的主要参数、平均流速的重要性、粘度及其影响。 * **流体流动类型:** 区分不同的流动类型、流动状态以及雷诺数(Reynolds number)的概念。 * **气体与液体流动的差异:** 重点比较气体和液体在管道中的流动特性。 * **流体连续性方程:** 介绍流体在管道中流动的基本守恒定律。 * **气体密度计算:** 涵盖标准流量和实际流量的计算,以及气体的密度计算方法。 * **摩擦系数确定:** 讲解在管道流动中摩擦系数的计算与确定。 * **实际案例分析:** 通过具体的工程案例,演示管道尺寸的优化过程。 本课程仅需约2小时的学习时间,便能帮助学员全面掌握管道尺寸优化的关键知识,并能进行实际的计算应用。讲师还为学员提供免费的答疑服务,对于希望深入了解管道尺寸优化工程原理的学生、工程师及教师群体,本课程极具参考价值。
One regular factor in flow rate design is the calculation of pipe size. To diminish capital cost, some engineers may decrease the pipe size and increase the velocity.Optimizing the pipe size and velocity of the fluid not only improves the system efficiency but can also increase the service life. Some of the issues faced during increased velocity and undersized piping:High velocity in pipelines promotes corrosion/pitting; piping may be repaired or replaced sooner than expected.Abrasives and Erosion can cause premature failureSurge pressures due to water hammer cause more damages at higher speed.This course is mainly focused on pipeline sizing considering velocity and pressure drop criteria. However, before directly getting into this, some background information is desired to be provided. Course was taught by Process Engineer working in oil and gas field to the group of bachelor and master students. The main aspects discussed via the course are:Fluid flow essentialsShear stressPrimary parameters for fluid flowSignificance of average velocity in calculationsViscosityFluid flow typesFlow regimes and Reynolds numberDifference between gas and liquid flowContinuity equation for fluid flowCalculation of density for gasesStandard vs actual flow ratesDetermination of friction factor through a pipeLine sizing performed on a real case problemAbove points have clearly been discussed during the course. This training can be really helpful for students, engineers and even teachers aiming to deliver line sizing essentials from engineering point of view. By spending only 2 hours, you can really understand the whole topic and further do practical calculations. Course instructor does also provide the service of answering questions for all course participants for free.
