  5. 5. Fluid Flow and Heat Transfer Simulations for Complex Industrial Applications : From Reynolds Averaged Navier-Stokes towards Smoothed Particle Hydrodynamics

    Författare :Md Lokman Hosain; Rebei Bel Fdhila; Konstantinos Kyprianidis; Erik Dahlquist; Hailong Li; Moncho Gomez Gesteira; Mälardalens högskola; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational Fluid Dynamics; Heat transfer; Industrial applications; Reynolds Averaged Navier-Stokes; Smoothed Particle Hydrodynamics; Energy enginnering; Thermal Management; Process control; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Optimal process control can significantly enhance energy efficiency of heating and cooling processes in many industries. Process control systems typically rely on measurements and so called grey or black box models that are based mainly on empirical correlations, in which the transient characteristics and their influence on the control parameters are often ignored.
