Flownex® SE can be used for academic purposes; learning and teaching the physical principles in the fields of heat transfer, fluid mechanics, and thermodynamics.

STUDENTS

A limited functionality Student Version is available free of charge from our website for any registered student. With the different physics models used in Flownex®, it is ideally suited to teach students the physical principles in the fields of Heat Transfer, Fluid Mechanics and Thermodynamics. We have ready-made material for these subjects which explains the theory, provides a lecturer’s class example and finally a student homework project.

TEACHERS & RESEARCHERS

In an academic environment Flownex® Simulation Environment can be a powerful research tool or classroom teaching aid. An academic license of Flownex® which is greatly discounted is available for purchase to universities for use in undergraduate teaching or student projects. Post-graduate students may obtain the full version of Flownex® for free over 6 months, with renewal after providing us with a progress report.

OVERVIEW

Flownex® Simulation Environment is a powerful research tool and classroom teaching aid used to demonstrate the physical principles in the fields of fluid mechanics, heat transfer, and thermodynamics. Flownex® SE determines pressure drop and heat transfer for the connected components of a complete system in steady state and transient, e.g. pumps or compressors, pipes, valves, tanks and heat exchangers.

Material on Bernoulli’s principle provides a fundamental explanation of energy conservation in fluid flow and the causes and effects of pressure loss. While the transfer though flat and cylindrical geometries is illustrated by Conduction and the change in temperature with pressure is fundamentally explained by the Joule – Thomson effect.

APPLICATIONS

FLUID MECHANICS

The theoretical summary aims to explain the fundamental calculation of steady-state pipe flow using the Bernoulli principle with pressure loss effects. The theory includes conservation of mass, momentum, and energy, as well as relations for static and stagnation fluid properties, Bernoulli’s principle, and the calculation of primary and secondary pressure losses.

The Flownex® SE network example and assignment dynamically illustrate the effect of pipe roughness and flow velocity on the energy and hydraulic grade line.

LECTURER’S EXAMPLE TO SHOW IN CLASS​

The Flownex® SE network with a graphical interface dynamically illustrates the effect of pipe roughness and flow velocity on the energy and hydraulic grade line. The example uses a short pipeline section with an elevation difference between the inlet and outlet (that holds pitot tubes and standpipes) that indicates the pressure difference.

STUDENT PROJECT TO USE AS ASSIGNMENT

A student assignment with results memorandum evaluates the knowledge and understanding of the students using either hand calculations or Flownex® as a software tool. The assignment expects the student to calculate the flow through a flow meter using specified pressure readings from the instrumentation.

HEAT TRANSFER

The theoretical summary aims to explain the fundamental calculation of conduction and convection heat transfer. The theory includes conservation of energy as well as relations for one-dimensional steady-state convection and conduction through a plane wall and cylindrical pipe geometries.

The Flownex® SE network example and assignment dynamically illustrate the difference between plane wall and cylindrical wall heat transfer with varying wall thickness.

LECTURER’S EXAMPLE TO SHOW IN CLASS

The Flownex® SE network with a graphical interface dynamically illustrates the difference between plane wall and cylindrical wall heat transfer with varying wall thickness. The example uses a heat transfer element and pipe combination which either model a tube or plane wall with water flowing on one side and air over the other.

STUDENT PROJECT TO USE AS ASSIGNMENT

A student assignment with results memorandum evaluates the knowledge and understanding of the students using either hand calculations or Flownex® as a software tool. The exercise expects the student to calculate and compare the air sidewall surface temperature of both the plane wall and tube scenarios using the same specified wall.

THERMODYNAMICS

The theoretical summary aims to explain the fundamental change in a fluid temperature with pressure. The theory includes the first law of thermodynamics, fluid property diagrams, ideal gas law relations and the Joule-Thomson coefficient.

The Flownex® SE network example and assignment dynamically illustrate the effect of varying throttling and system temperatures on pressure-temperature relations of fluids.

LECTURER’S EXAMPLE TO SHOW IN CLASS

The Flownex® SE network with graphical interface dynamically illustrates the effect of varying throttling and system temperatures on pressure-temperature relations of fluids. The example uses a pressurized tank blowing off to another reservoir through a short pipeline with a restrictor. Helium, Nitrogen and air are used as fluids.

STUDENT PROJECT TO USE AS ASSIGNMENT

A student assignment with results memorandum evaluates the knowledge and understanding of the students using either hand calculations or Flownex® as software tool. The exercise expects the student to calculate the pressures and temperatures of a basic heat pump system using a pump, valve and specified heat transfer requirement.

From rapid rocket engine cycle designs to detailed component development: Flownex® has the capability to model and simulate large interconnected rocket engine systems. Using Flownex®, pre-burners with complex combustion reactions can be simulated, flow control strategies can be investigated, turbopumps with real-time power matching can be implemented and much more.

"Equipping the lecturer to ease teaching of fundamental fluid mechanics, heat transfer and thermodynamics principles."

Liquid-fuelled Rocket engines have come a long way since the first-ever rocket launch by Robert Goddard on March 16th 1926. Today more sophisticated rockets have been developed, such as the SpaceX Raptor engine. Different liquid rocket cycles have been designed in the past few decades: improving efficiency, power, and safety. This has led to time consuming and costly physical testing and design calculations. To reduce R&D cost and development time, 1D system simulation can be incorporated into the design process.
