Fluid Network Interfaces Library

Components that connect networks and domains

Use these blocks to connect different domain networks. You can connect multiple domains with interface blocks to make use of features in either library.

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.

Featured Examples

EV Battery Cooling System

This demo shows an Electric Vehicle (EV) battery cooling system. The battery packs are located on top of a cold plate which consists of cooling channels to direct the cooling liquid flow below the battery packs. The heat absorbed by the cooling liquid is transported to the Heating-Cooling Unit. The Heating-Cooling Unit consists of three branches to switch operating modes to cool and heat the battery. The Heater represents an electrical heater for fast heating of the batteries under low temperature conditions. The Radiator uses air-cooling and/or heating when the batteries are operated stably. The Refrigerant system is used for cooling the overheated batteries. The refrigeration cycle is represented by the amount of heat flow extracted from the cooling liquid. The system is simulated under either FTP-75 drive cycle or fast charge scenarios with different environment temperatures.

Liquid Air Energy Storage System

Models a grid-scale energy storage system based on cryogenic liquid air. When there is excess power, the system liquefies ambient air based on a variation of the Claude cycle. The cold liquid air is stored in a low-pressure insulated tank until needed. When there is high power demand, the system expands the stored liquid air to produce power based on the Rankine cycle.

Vehicle HVAC System

Models the heating and cooling system of a passenger car. The cabin is represented as a volume of moist air exchanging heat with the external environment. The blower drives moist air through the evaporator, blend door, and heater core before returning to the cabin. The blend door controls the amount of air flow through the heater core. The recirculation door controls whether air is brought in from the external environment or from within the cabin.
