Gradient intersection method
WebJun 12, 2024 · The gradient intersect method uses the fact that the flow rate downstream of the leak is lower than the flow rate upstream. Thus, the pressure drop per unit length … WebThen there is exactly one vector that minimizes J ( p) and this vector is the solution of the linear equation, (57) A p = b. The proof of this statement is straightforward. Let us compute the gradient of J: ∇ J = A p − b. To get the above expression we have used A = A T. The gradient of J is therefore equal to zero if A p = b.
