Assessment of continuous and discrete adjoint method for sensitivity analysis in two-phase flow simulations
Guojun Hu, Tomasz Kozlowski
The efficient method for computing the sensitivities is the adjoint method. The cost of solving an adjoint equation is comparable to the cost of solving the governing equation. Onc…
