    • A new hybrid optimization method, application to a single objective active flow control test case 

      Coma Company, Martí; Monshi Tousi, Navid; Pons Prats, Jordi; Bugeda Castelltort, Gabriel; Bergadà Granyó, Josep Maria (Multidisciplinary Digital Publishing Institute, 2022-04-12)
      Article
      Open Access
      Genetic Algorithms (GA) are useful optimization methods for exploration of the search space, but they usually have slowness problems to exploit and converge to the minimum. On the other hand, gradient based methods converge ...

    • Active flow control optimisation on SD7003 airfoil at pre and post-stall angles of attack using synthetic jets 

      Monshi Tousi, Navid; Coma Company, Martí; Bergadà Granyó, Josep Maria; Pons Prats, Jordi; Mellibovsky Elstein, Fernando; Bugeda Castelltort, Gabriel (2021-06-10)
      Article
      Open Access
      The use of Active Flow Control (AFC) technologies to modify the forces acting on streamlined bodies is one of the most active research fields in aerodynamics. For each particular application, finding the optimum set of AFC ...

    • Active flow control optimization on Selig Donovan 7003 airfoil 

      Monshi Tousi, Navid (Universitat Politècnica de Catalunya, 2023-06-16)
      Doctoral thesis
      Open Access
      (English) The PhD focuses on the study of the flow around an airfoil at different Angles of Attack (AoA) with and without the implementation of Active Flow Control (AFC), while maintaining the Reynolds number constant at ...

    • Discharge coefficients of a heavy suspension nozzle 

      Río Cano, Carlos; Monshi Tousi, Navid; Bergadà Granyó, Josep Maria; Comas Amengual, Ángel (MDPI, 2021-03-15)
      Article
      Open Access
      The suspensions used in heavy vehicles often consist of several oil and two gas chambers. In order to perform an analytical study of the mass flow transferred between two gas chambers separated by a nozzle, and when ...

    • Large eddy simulation of optimal synthetic jet actuation on a SD7003 airfoil in post-stall conditions 

      Monshi Tousi, Navid; Bergadà Granyó, Josep Maria; Mellibovsky Elstein, Fernando (2022-08)
      Article
      Open Access
      Aerodynamic performances may be optimised by the appropriate tuning of Active Flow Control (AFC) parameters. For the first time, we couple Genetic Algorithms (GA) with an unsteady Reynolds-Averaged Navier-Stokes (RANS) ...

    • Optimization of synthetic jet actuation on a SD7003 airfoil in stall conditions 

      Monshi Tousi, Navid; El Mansy, Reda; Mellibovsky Elstein, Fernando; Bergadà Granyó, Josep Maria (2022)
      Conference report
      Open Access
      We optimise a set of Synthetic Jet (SJ) Active Flow Control (AFC) parameters on a SD7003 airfoil in order to maximise lift and aerodynamic efficiency. 2D-RANS with the Spallart Almaras (SA) turbulence model is employed in ...

    • Square cylinder downstream of two different-velocity streams 

      El Mansy, Reda; Monshi Tousi, Navid; Bergadà Granyó, Josep Maria; Mellibovsky Elstein, Fernando (2022)
      Conference lecture
      Open Access
      We study the flow past a square cylinder immersed in the wake of an upstream splitter plate separating two different-velocity streams. The bottom stream Reynolds number, ReB = 56 is kept constant for all cases, while the ...
