About Course

Fluid power has the highest power density of all conventional power-transmission technologies. Learn the benefits and limitations of fluid power, how to analyze fluid power components and circuits, and how to design and simulate fluid power circuits for applications. In this course, you will be introduced to the fundamental principles and analytical modeling of fluid power components, circuits, and systems. You will learn the benefits and limitations of fluid power compared with other power transmission technologies; the operation, use, and symbols of common hydraulic components; how to formulate and analyze models of hydraulic components and circuits; and how to design and predict the performance of fluid power circuits. This course is supported by the National Science Foundation Engineering Research Center for Compact and Efficient Fluid Power, and is endorsed by the National Fluid Power Association, the leading industry trade group in fluid power.

Course Syllabus

This will be a busy week diving into valves and pumps. We will discuss how basic valves function, how to use them in hydraulic circuits, and how to calculate pressure drop for a given flow rate, or vice versa. The videos will directly address the discussion on the forum about seeing hydraulic components working in real world circuits. In our discussion of pumps we will look at many different positive displacement pumps, exploring flow ripple and pump efficiency, look at the supporting components that form a hydraulic power supply, and see how we can make a transmission with a hydraulic pump and a motor. We are now into the heart of this course; we hope you enjoy seeing the components come together into useful circuits.

Course Introduction

Fundamentals of Fluid Power Systems Fluid power systems operate at high pressure, high temperature, and low pressure and/or pressure-domain devices. Understanding the basic properties of fluid power systems is important for engineers, designers, and implementers. This course covers the engineering principles behind fluid power systems, the engineering design of fluid power components, and the modeling and simulation of fluid power circuits. Upon completing this course, you will be able to: 1. Describe fluid power systems 2. Design fluid power components 3. Model and solve fluid power circuitsDesign Principles Fluid Power Systems Design Problems Simulating Fluids Fundamentals of Fluid-Solid Interactions In this course, we will learn about the basic properties and interactions of fluids at low pressure, temperature, pressure and pressure. We will start by introducing the different phases of fluid-solid interactions: phase transitions, phases of duality, phases of convergence, and phases of interaction. We will learn about the physical properties and behavior of the phases and their dependence on the solvent. We will apply these concepts to understand and analyze the energy and chemical behavior of the various phases of fluid-solid interactions. Learning Outcomes. By the end of this course, you will be able to describe the physical, chemical, and behavior of the different phases of fluid-solid interactions, and their dependence on the solvent.

Fluid power Fluid power is the use of fluids under pressure to generate, control, and transmit power. Fluid power is subdivided into hydraulics using a liquid such as mineral oil or water, and pneumatics using a gas such as air or other gases. Compressed-air and water-pressure systems were once used to transmit power from a central source to industrial users over extended geographic areas; fluid power systems today are usually within a single building or mobile machine.
British Fluid Power Association The British Fluid Power Association is a trade association in the United Kingdom that represents the hydraulic and pneumatic equipment industry, utilising properties of fluid power.
Power-law fluid A Newtonian fluid is a power-law fluid with a behaviour index of 1, where the shear stress is directly proportional to the shear rate:
Power-law fluid A power-law fluid, or the Ostwald–de Waele relationship, is a type of generalized Newtonian fluid for which the shear stress, "τ", is given by
Power-law fluid Also known as the Ostwald–de Waele power law this mathematical relationship is useful because of its simplicity, but only approximately describes the behaviour of a real non-Newtonian fluid. For example, if "n" were less than one, the power law predicts that the effective viscosity would decrease with increasing shear rate indefinitely, requiring a fluid with infinite viscosity at rest and zero viscosity as the shear rate approaches infinity, but a real fluid has both a minimum and a maximum effective viscosity that depend on the physical chemistry at the molecular level. Therefore, the power law is only a good description of fluid behaviour across the range of shear rates to which the coefficients were fitted. There are a number of other models that better describe the entire flow behaviour of shear-dependent fluids, but they do so at the expense of simplicity, so the power law is still used to describe fluid behaviour, permit mathematical predictions, and correlate experimental data.
Power-law fluid Just like a Newtonian fluid in a circular pipe gives a quadratic velocity profile (see Hagen–Poiseuille equation), a power-law fluid will result in a power-law velocity profile,
Fluid power A fluid power system has a pump driven by a prime mover (such as an electric motor or internal combustion engine) that converts mechanical energy into fluid energy, Pressurized fluid is control and directed by valves into an actuator device such as a [hydraulic cylinder]] or pneumatic cylinder, provides linear motion, or a hydraulic motor or pneumatic motor, to provide rotary motion or or torque. Rotary motion may be continuous or confined to less than one revolution.

Hydraulic fluid Power steering fluid is a subtype of hydraulic fluid. Most are mineral oil or silicone based fluids, while some use automatic transmission fluid, made from synthetic base oil.

Carreau fluid Carreau fluid behaves as a Newtonian fluid and at high shear rate (formula_13) as a power-law fluid.
Fluid power Machinery operated by fluid power covers a wide range of applications in industry. Mobile excavating equipment uses hydraulic systems. Automated production lines may use pneumatic or hydraulic systems to position work pieces or move tools. Variable-flow control valves and position sensors may be included in a servomechanism system for precision machine tools.
Fluid bearing Fluid bearings generally have very low friction—far better than mechanical bearings. One source of friction in a fluid bearing is the viscosity of the fluid. Hydrostatic gas bearings are among the lowest friction bearings. However, lower fluid viscosity also typically means fluid leaks faster from the bearing surfaces, thus requiring increased power for pumps or friction from seals.
Hydraulic fluid The primary function of a hydraulic fluid is to convey power. In use, however, there are other important functions of hydraulic fluid such as protection of the hydraulic machine components. The table below lists the major functions of a hydraulic fluid and the properties of a fluid that affect its ability to perform that function:
First-order fluid A first-order fluid is another name for a power-law fluid with exponential dependence of viscosity on temperature.
