1. 1. Solving the incompressible Navier-Stokes equations in 3-D to model gas flow in a room

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Fredrik Malmström; [2024]
   Keywords : ;

   Abstract : The thesis proposes to model the flow of gases in a room by solving the incompressible Navier-Stokes equations in three dimensions. The transportationof scalars such as temperature and concentration of CO2 is modeled by solving the advection-diffusion equation, and the effects of temperature on thevelocity is accounted for by employing the Boussinesq approximation.

3. 2. Lid driven cavity flow using stencil-based numerical methods

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Hannes Juujärvi; Isak Kinnunen; [2022]
   Keywords : Finite differences; incompressible Navier-Stokes equations; lid driven cavity flow; benchmark problem; RBF-FD-LS; FDM; accuracy; computational cost; stream function-vorticity formulation;

   Abstract : In this report the regular finite differences method (FDM) and a least-squares radial basis function-generated finite differences method (RBF-FD-LS) is used to solve the two-dimensional incompressible Navier-Stokes equations for the lid driven cavity problem. The Navier-Stokes equations is solved using stream function-vorticity formulation. READ MORE

4. 3. 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

5. 4. Finite Element Approximations of 2D Incompressible Navier-Stokes Equations Using Residual Viscosity

   University essay from Uppsala universitet/Institutionen för teknikvetenskaper

   Author : William Sjösten; Victor Vadling; [2018]
   Keywords : Finite element method; incompressible Navier-Stokes equations; residual based artificial viscosity; stabilization; adaptive method; Chorin s method; IPCS; Crank-Nicholson s method; benchmark problems; CPU-time; accuracy;

   Abstract : Chorin’s method, Incremental Pressure Correction Scheme (IPCS) and Crank-Nicolson’s method (CN) are three numerical methods that were investigated in this study. These methods were here used for solving the incompressible Navier-Stokes equations, which describe the motion of an incompressible fluid, in three different benchmark problems. READ MORE

6. 5. CFD Simulation of Jet Cooling andImplementation of Flow Solvers inGPU

   University essay from KTH/Numerisk analys, NA

   Author : Md. Lokman Hosain; [2013]
   Keywords : ;

   Abstract : In rolling of steel into thin sheets the final step is the cooling of the finished product on the Runout Table. In this thesis, the heat transfer into a water jet impinging on a hot flat steel plate was studied as the key cooling process on the runout table. The temperature of the plate was kept under the boiling point. READ MORE
