Hydraulics (Isothermal) Library

Specialized components for modeling fluid networks in the Hydraulics (Isothermal) domain

Isothermal liquid networks do not undergo temperature or viscosity changes due to any processes occurring in or around the network, but can support elevated or reduced temperatures.

In R2020a, the Isothermal Liquid library was introduced as a mass flow rate-based alternative to the Hydraulics (Isothermal) volumetric flow rate-based library. The Isothermal Liquid library introduces block usability improvements. For more information on converting models with Hydraulics (Isothermal) blocks to use Isothermal Liquid blocks, see: Upgrading Simscape Fluids Models Containing Hydraulics (Isothermal) Blocks.

If a specific component does not yet exist in a domain library, you can build your own using the Simscape language. For more information, see Creating Custom Components.

  • Accumulators
    Pressurized chambers for hydraulic energy storage and pulsation smoothing.
  • Hydraulic Cylinders
    Linear and rotary actuators for one- and two-way motion control.
  • Hydraulic Utilities
    Hydraulic fluid properties and reservoirs.
  • Local Hydraulic Resistances
    Bends, elbows, and other local resistances to fluid flow.
  • Low-Pressure Blocks
    Pipes and tanks with fluid elevation included in pressure calculations.
  • Orifices
    Local flow restrictions of fixed and variable size.
  • Pipelines
    Conduits for fluid transport and machine lubrication.
  • Pumps and Motors
    Fixed- and variable-displacement devices for mechanical-hydraulic energy conversion.
