GEOG 225 Media Assignment

University of Waterloo GEOG 225 Media Assignment Introduction For the following Media Assignment, I have decided to use a current issue during the times of a global pandemic, Coronavirus also known as Covid-19. I have reviewed several new articles and eventually decided to elucidate the correlation between Air pollution and Covid-19. Reviewed article This is a following article from BBC which caught my eye. It delineates the correlation between Covid-19 and air pollution especially in ...

AerE 546 Lecture 14 Algebraic grid generation

Algebraic grid generation A. A simple, algebraic grid. Grid is a set of points connected by lines (Mesh is the set of points joined into cells.) GRID MESH General idea: mesh surface, propagate into interior -- sometimes by solving elliptic boundary value problem for x(i,j). Choose points on wall, connect them, place tic marks along connecting line = grid; i.e., define surfaces by ( xin(i),yin(i) ) Specify x,y inner and outer then: x(s) = xin + ( xout - xin ) s (0≤ s ≤1) DO i=1,I ...

AerE 546 Lecture 15 Equations on curvilinear grids: “metric” tensor

Recall 2-surface method. Grid lines are curved; can use finite diff or finite vol. Former here; will be lectures on latter, but FYI. Actually, grid is a set of points organized into cells. Equations on curvilinear grids: “metric” tensor A. Computational and physical space Grid is not in x-y direction: Grid generation produces [x(i,j),y(i,j)]. Now use that to solve equations. Map from computational to physical. Think of i,j as a grid in ξ - η space. For example δf/δξ = (f(i+1,j...

AerE 546 Lecture 16 (Review finite-diff. and metrics)

(Review finite-diff. and metrics) Second derivatives: Evaluate ∂2ψ/∂2x as ∂xF with F = ∂xψ Outside, then in, but iterated central would give 5 i-points. Wrong: δξ(F) =( Fi+1 - Fi-1 )/2 with F= δξψ → [(ψi+2 -ψi) - (ψi - ψi-2 )]/4. Instead use: ( Fi+1/2 - Fi-1/2 )/2 → [(ψi+1 -ψi) - (ψi - ψi-1 )]/4. Fi+1/2 = value on cell face Fi+1 is data at cell center. Or recall formulating equations in conservation form: Flux in - Flux out + source = rate of change inside c....

AerE 546 Lecture 17 Finite volume method

Finite volume method Natural for unstructured meshed. Also, working with fluxes leads into hyperbolic equations. A. Recall origin of p.d.e.ʼs Donʼt take second step: apply discretization to the integral balance. Control volume is polyline (polyhedron in 3-D). Divergence theorem (Gaussʼ) is used in f.v. method. Rationale: f = ∫df/dx dx but now f ! ∫F·dS and df/dx dx ! ∫ ∇·F dV =∫ ∇·F dS dxn =∫ dF/dxn dxn dS = ∫n·FdS Divergence theorem <-> fundamental theorem...
