User Experience
  • A User Interface can act as a barrier to leveraging the power of the software
  • FloMASTER V8 Simplifies the User Experience not the power of the software
  • Increase User Productivity
    • SIMPLIFY: Remove complexity and value-less user steps
    • AUTOMATE: Remove repetitive tasks
    • DISCOVERY: Progressive discovery
  • Accelerate Learning
    • Example networks etc.
    • Search 
    • Improved Help
  • Remove Unnecessary Admin
    • SIMPLIFY: Simplify Database, license management through FloMASTER
    • AUTOMATE: All DBA level tasks

MBD: Simulation Based Characterisation

  • A new workflow that utilises the strengths of FloEFD’s 3D CFD capabilities to characterize multi arm geometries for use in FloMASTER
  • The resulting FloMASTER ‘N-Arm’ models offer significant value;
    • Ability to capture the performance of complex multi branch geometries for use in FloMASTER within a single component from 3D CAD Geometry
    • Avoid the need to build physical test models

MBD: Script Based Components

  • Allow users to define a simple component using a script
  • Script defines pressure and thermal response, e.g. hand calcs, apply curves and surfaces
  • Defaults to perfect mixing if no thermal response specified
  • Works with all circuit types and fluids
  • Makes it easy to access flow and fluid properties at each arm
  • Script Based Components allow;
    • Empower AEs, re-sellers, clients to build simple components 
    • Automates calculation of A & B – even for complex pressure response and many arms, e.g 4 arm junction, jet pump
    • Replace in-house codes - Makes it easy for users to put their IP into FloMASTER

MBD: Automation Launcher

A new capability to enable System Simulation to be more widely used in Engineering Companies by leveraging Microsoft Excel
  • Automatic generation of Excel front end to FloMASTER System Model
  • Allow non-expert users to access the model in a controlled and familiar environment
  • Maximize the value of the product

New Control Elements

  • 16 new control components
  • Allows controls systems to be modelled using a building block approach with base mathematical functions
  • Enhances FloMASTER’s Transient solution
    • A convenient means to understand fluid system response to control inputs

What is Waste Heat Recovery (WHR)? 

  • Automotive WHR allows some of the 60%+ of fuel energy lost to surroundings to be recovered to 
    • Improved powertrain efficiency
    • Reduce vehicle CO2 emissions
  • Most large OEMs & Tier 1’s have WHR R&D programs with Heavy Truck and Luxury Cars likely to be principal applications
    • Class 8 trucks carry 70% of all freight and use >20% of all fuel consumed in U.S.
  • Organic Rankine Cycle (ORC)
    • Arguably most promising WHR technology
    • Potential for 5% fuel economy improvement for long HD haul operations 
    • Increases viability of alternative energy sources through recovery of ‘low grade’ heat
  • Also significant ORC interest for mass market
    • Could supply 100% vehicle accessory load in LD vehicle on EPA Highway Drive Cycle

Mentor Graphics ORC-WHR Programme

  • What is Mentor’s ORC-WHR programme?
    • Strategic enhancement to FloMASTER’s core thermo-fluid capability
    • Leverages NIST REFPROP curves & surfaces capability for faster simulation
    • Primarily aimed at Automotive Vehicle Thermal Management but flexible enough for small scale Power Generation
  • Key Capabilities
    • Models entire ORC layouts using wide range of components
    • Reports energy flows & system efficiency
  • USP’s
    • Speed up component selection and system optimisation through the new ‘VC Circuit Manager’ component
