Lab in numerical simulation of flow and heat transfer

Also listed as: מעבדה בסימולציות נומריות בזרימה ומעבר חום

A computational fluid dynamics lab where you run the solver, not watch it. Mesh, boundary conditions, turbulence model, convergence, and then the part nobody teaches: deciding whether the answer is true.

Comes after

  • Fluid mechanics 1
  • Heat transfer

What it covers

Method

  • Governing equations and their discretisation, finite volume and finite difference
  • Mesh generation and mesh quality, y+ and near-wall treatment
  • Boundary conditions and solver settings
  • Turbulence models: k-ε, k-ω SST, and how the choice changes the answer
  • Residuals, convergence, verification and validation

The standard projects

  • Lid-driven cavity
  • Flat-plate boundary layer against the Blasius solution
  • Fully developed pipe flow
  • Backward-facing step and reattachment length
  • Conjugate heat transfer
  • Natural convection in an enclosure

Results worth carrying out

  • Wall coordinate

    y+=uτ yν,uτ=τwρy^+ = \frac{u_\tau\, y}{\nu}, \qquad u_\tau = \sqrt{\frac{\tau_w}{\rho}}
  • Courant number

    CFL=u ΔtΔx\mathrm{CFL} = \frac{u\,\Delta t}{\Delta x}
  • Eddy viscosity, two-equation closure

    μt=ρCμk2ϵ\mu_t = \rho C_\mu \frac{k^2}{\epsilon}

Figures worth knowing

  • Mesh and mesh-quality plots
  • Velocity and temperature contours, streamlines and vectors
  • y+ maps
  • Residual histories

This map tells you what a course contains. The summaries, the tutoring and the people who already took it are the part you get by joining.

The topic outlines are not official syllabi. The university publishes a catalogue blurb per course, not lecture-by-lecture material, so each outline describes what a course of that name, at those hours, with those prerequisites teaches at engineering schools generally, cross-checked against the standard textbook for the subject. Treat it as an informed map, not as a transcript of the lectures.
