1 Simulation Based Development About COMSOL Worldwide offices +480 employees More than users Fast growing Thure Ralfs, Managing Director, COMSOL A/S Hilde Larsson, Application engineer, CFD Leading provider of Multiphysics software 1

2 Agenda Simulation Based Development Checking in on the Revolution Simulation Based Development Why & What CFD and measurements How & Benefits Who should be involved We are in the middle of a Revolution! Simulation Revolution What is a revolution? When looking back you can identify events that took place in a relative short timespan that completely changed the way we do things. Copyright 2016 COMSOL.

3 Looking back in Years Last 4000 time to Develop Mathamatics Last 400 To develop Calculus & physics Last 60 Develop Computers & Numerics Last 30 Commercial FEA/CAE tools Last 5-10 High Fidelity Virtual Prototypes Mathematics the language of prediction 3400 BC Sumerians introduces 1st numbering system (Mesopotamia) 530 BC Pythagoras theorem (School in Croton) 400 BC Pingala (India) introduces the concept of zero 150 BC Negative numbers introduced in China 300 Indian mathematicians users 0 as a decimal digit 500 Arybhata (India) introduces the trigonometric functions 820 Al-Khwarismi (Persia) writes the Al-Jabr which introduces systematic technics for solving linear and quadratic equations 3

4 Mathematics and Physics The Scientific Revolution (16th and 17th Centuries) 1665 Newton develops calculus - Classical Mechancis 1733 Bernoulli theory of gasses, vibration of elastic bar 1762 Lagrange discovers the Divergence Theorem 1840 Navier-Stokes Equations 1861 Maxwell publishes his equations Enables the industrial revolution (mid 18th to mid 19th century) A Revolution Waiting to Happen So here we are A greet set of physics laws Elegantly described by mathematical equations Which we don t know how to solve! 4

5 Democratization of Analysis 300 BC Babylonians invent the abacus 1622 Slide Ruler invented 1961 First electronic Desktop Calculator 1964 IBM 360 Mainframe 1970 Pocket calculator 1976 Cray 1 Supercomputer 1976 Appel 1; 1977 Appe II; 1984 IBM PC 2007 Calculator on your smartphone Today Multiphysics from your smartphone The Information Age Computer Revolution Looking back on Innovation Trail and Error The Scientific Revolution 16th and 17th centuries Algebraic approximation Then Trial & Error Industrial Revolution mid 18th to mid 19th century Lumped ODE s Then Trial & Error Information Age 20th and early 21st century Lumped ODE s -> Prototyping Then some simulation (FEA) on what failed 5

6 The Simulation Revolution Looking back Standing on the back of 4000 years of math and 400 years of physics Scientific Revolution (16th & 17th centuries) Industrial Revolution (Mid 18th to mid 19th) Information Age (Computer Revolution) (Late 20th to Early 21th) Simulation Revolution Finally we can solve the physics equations and predict Then some prototyping System Simulation and then build To Come Happening right Now ? Simulation Based Development Economy Lower development cost Faster time to market Minimize risks Bottom line Resources Throughout the organization Free R&D resources Faster solutions Save time Technical Gain understanding Document knowledge Optimize products Competitive edge 6

7 Simulation Based Development Virtual prototypes of devices or processes Using simulation throughout the organization High fidelity virtual prototypes multiphysics More than one physics acting at the same time Coupling between physics Fluid-Structure Interaction of a Solar Panel Inductive Heating Porous Reactor Acoustics Speaker Systems 7

8 RANS Lagrange-Euler Non-Newtonian Richards Rotating flow Newtonian Euler-Euler Non-Isothermal flow Single phase flow Free flow Porous media Super sonic flow Multiphase flow What is fluid dynamics and CFD? Slip flow Thin film flow Continuum flow Fracture flow Creeping flow Brinkman High Mach Number Laminar Darcy Pipe flow Electrokinetic Low Mach Number Compressible flow Molecular flow Turbulent Transitional flow Algebraic Multiphase Separated flow Multiphase Disperse flow Isothermal flow Magnetokinetic Copyright 2016 COMSOL.

See Weakly compressible flow Water Treatment Reactor Water treatment reactors are used to produce clean and safe drinking water Understand and improve the system through virtual experiments 8

9 Water Treatment Reactor Tracer experiments can be used to Validate the model with experimental data Evaluate the mixing and residence times Outlet Inlet Water Treatment Reactor The tracer concentrations can be virtually monitored in the basin Evaluate the positions of the measurement points Useful for optimization 9

10 Ultrasound Flow Meter In COMSOL it is possible to couple several different physics An ultrasound flow meter determines flow based on the time difference of a pulse traveling from upstream or downstream between a source and receiver Ultrasound Flow Meter Surface Acoustic Pressure [Pa] 10

11 Coriolis Flow Meter A Coriolis flow meter is another device for measuring flow in a pipe Multiphysics simulation combining CFD, structure dynamics and acoustics Coriolis Flow Meter The geometry and load is symmetric but the deflection is not due to the background flow The phase differences are used to determine the flow in the pipe 11

12 Microchannel Dispersion Shape optimization can be used to improve product designs Here this is illustrated on a 100 µm wide channel Microchannel Dispersion The sample is smeared out once reaching the detection area Why could this be a problem? Why does it happen? How can it be avoided? 12

13 Microchannel Dispersion Shape optimization has been applied on the inner boundary In the optimized geometry the sample remains gathered Shape optimization leads to improved products and designs Tesla Microvalve 13
