  1. 21. Numerical Modeling of Atomization in Spray Systems

    Författare :Michele Pütz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; spray modeling; quadrature-based moment methods; atomization; numerical simulation; Multiphase; population balance equations;

    Sammanfattning : Dispersed multiphase flows refer to dynamic systems comprising two or more phases where at least one phase is in the form of fine particles evolving in and interacting with a surrounding fluid. Spray systems fall into that category. LÄS MER

  3. 22. On Model Libraries for Thermo-hydraulic Applications

    Författare :Jonas Eborn; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling; simulation; Matematik; Automation; Termisk teknik; control systems; nonlinear models; parameter estimation; proces s control; thermo-hydraulic systems; model validation; Thermal engineering; applied thermodynamics; termodynamik; Automatiska system; robotics; control engineering; reglerteknik; robotteknik; Mathematics; object-oriented;

    Sammanfattning : Mathematical modelling and simulation are important tools when dealing with engineering systems that today are becoming increasingly more complex. Tightly integrated production and process optimization are trends that give rise to heterogeneous systems, which are difficult to handle without expertise in several engineering disciplines. LÄS MER

  4. 23. Formal Methods for Scalable Synthesis and Verification of Autonomous Systems : Mission Planning and Collision Avoidance

    Författare :Rong Gu; Cristina Seceleanu; Kristina Lundqvist; Eduard Paul Enoiu; Rajeev Alur; Mälardalens universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; autonomous agents; synthesis; verification; planning; collision avoidance; formal methods; model checking; Computer Science; datavetenskap;

    Sammanfattning : Autonomous systems (a.k.a., agents) are often designed to move and execute tasks, without or with little human intervention. LÄS MER

  5. 24. Safety, Security, and Semantic Aspects of Equation-Based Object-Oriented Languages and Environments

    Författare :David Broman; Peter Fritzson; Henrik Nilsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Modeling; Simulation; Equation-Based; Object-Oriented; Modelica; Type System; Semantics; Language Safety; Secure Simulation; Computer science; Datavetenskap;

    Sammanfattning : During the last two decades, the interest for computer aided modeling and simulation of complex physical systems has witnessed a significant growth. The recent possibility to create acausal models, using components from different domains (e.g., electrical, mechanical, and hydraulic) enables new opportunities. LÄS MER

  7. 25. On Gas Dynamics of Exhaust Valves

    Författare :Marcus Winroth; P. Henrik Alfredsson; Ramis Örlü; Knud Erik Meyer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exhaust valve; poppet valve; dynamic valve; engine modeling; discharge coefficient; Avgasventil; rörlig ventil; motorsimulering; utsläppskoefficient; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : With increasing effects of global warming, efforts are made to make transportationin general more fuel efficient. When it comes to internal combustion engines,the most common way to improve fuel efficiency is through ‘downsizing’. Downsizingmeans that a smaller engine (with lower losses and less weight) performsthe task of a larger engine. LÄS MER
