Heat Recovery System for a Geothermal Heat Pump
Geothermal heating is an environmentally friendly and energy-efficient method to supply modern and well insulated houses with heat. Heat exchangers placed at a sufficient depth in the ground below the house utilize subsurface heat, where temperatures are almost constant throughout the ... En Savoir Plus
Cooling of an Injection Mold
This model shows how you can use the Non-Isothermal Pipe Flow interface together with the Heat Transfer in Solids interface to model the cooling of a injection molded polyurethane part for a car steering wheel. The equations describing the cooling channels are fully coupled to the heat ... En Savoir Plus
Acoustics of a Pipe System with 3D Bend and Junction
This tutorial shows how to model the propagation of acoustic waves in large pipe systems by coupling the *Pipe Acoustics* interface to the *Pressure Acoustics* interface. The tutorial is set up in both the time domain and the frequency domain. 1D pipe acoustics is used to model the ... En Savoir Plus
Coupled Analysis of Flow and Stress in a Pipe
In this tutorial model, the flow in a pipe with a bend is computed using the Pipe Flow interface. The computed fluid load is used as input to a stress analysis in the Pipe Mechanics interface. Gravity loads from the pipe and fluid are also taken into account. En Savoir Plus
Convective Flow in a Heat Exchanger Plate
This example models flow in a microchannel heat exchanger by coupling a Laminar Flow interface in 3D to a Pipe Flow interface. By the use of the Pipe Flow interface to model the flow in the microchannels the problem size is significantly reduced. This model showcases the Pipe Connection ... En Savoir Plus
Water Hammer
When a valve is closed rapidly in a pipe network it gives rise to a hydraulic transient known as a water hammer. The propagation of these hydraulic transients can in extreme cases cause failures of pipe systems caused by overpressures. This is a model of a simple verification pipe system ... En Savoir Plus
Insulation of a Pipeline Section
As oil flows through a pipeline section heat is released due to the work of internal friction forces in the fluid. With good insulation of the pipeline, this generated heat can be used to avoid preheating of the oil, despite the fact that it is to be transported in a cold environment ... En Savoir Plus
Discharging Tank
This tutorial model illustrates how to calculate the pressure drop and initial flow rate in a pipe system connected to water tank. The Pipe Flow interface contains ready to use friction models accounting for the surface roughness of pipes as well as pressure losses in bends and valves. En Savoir Plus
Geothermal Heating from a Pond Loop
Ponds and lakes can serve as thermal reservoirs in geothermal heating applications. In this example, fluid circulates underwater through polyethylene piping in a closed system. The pipes are coiled in a slinky shape and grouped onto sleds. The Non-isothermal Pipe Flow interface sets up ... En Savoir Plus
