Continuity equation in spherical coordinate

WebJan 1, 2014 · Naturally, the continuity equation ( 1.6) or ( 1.8) expresses the mass conservation. In the absence of sources or sinks, the amount of matter leaving a certain volume of the fluid is the same as the mass reduction in the same volume. In other words, the density in a certain volume element varies according to the flow in or out of the element. Web1.1 The Continuity equation in spherical coordinates Using the vector form of the continuity equation, we can reformulate it for different coordinate sys-tems relevant to specific problems by expanding the divergence operator ∇· appropriately. In spherical coordinates, we have ∂ρ ∂t + 1 r2 ∂ ∂r ρr2∂v r + 1 rsinθ ∂ ∂θ (ρv ...
