  1. 1. A Fractional Step Zonal Model and Unstructured Mesh Generation Frame-work for Simulating Cabin Flows

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Sergi Tarroc Gil; [2021]
    Keywords : Zonal Model; Thermal Comfort; Fluid Simulation; Aircraft Cabin Design; NURBS; Morphing; Radial Basis Functions; Meshing; Co-located Mesh; Unstructured Mesh; Mesh Quality; Mesh Smoothing; Enlarged Orientation Theorem; Fractional Step Method; Boussinesq; Adam Bashforth; Helmholtz-Hodge Theorem; Rhie and Chow; Difference Schemes; Gradient Evaluation; Differential Heated Cavity; Driven Cavity; Draught Rate;

    Abstract : The simulation of physical systems in the early stages of conceptual designs has shown to be a key factor for adequate decision making and avoiding big and expensive issues downstream in engineering projects. In the case of aircraft cabin design, taking into account the thermal comfort of the passengers as well as the proper air circulation and renovation can make this difference. READ MORE

  2. 2. Validation of Black-and-White Topology Optimization Designs

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Sharath Chandra Garla Venkatakrishnaiah; Harivinay Varadaraju; [2021]
    Keywords : Topology Optimization; 88-line code; CAD; post-processing; geometry smoothing; Savitzky-Golay filter; Ramer-Douglas-Peucker algorithm; interpolation; tan-h filter; threshold projection filter;

    Abstract : Topology optimization has seen rapid developments in its field with algorithms getting better and faster all the time. These new algorithms help reduce the lead time from concept development to a finished product. Simulation and post-processing of geometry are one of the major developmental costs. READ MORE

  3. 3. Geometric Shape Preservation in Adaptive Refinement of Finite Element Meshes

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Ashraful Kadir; [2010]
    Keywords : ;

    Abstract : This thesis presents a vertex repositioning based boundary smoothing technique so that the finite element mesh, as refined, converges to the geometric shape of the domain. Adaptive mesh refinements based on a posteriori error estimates is already available within FEniCS, a free software for automated solution of differential equations. READ MORE
