Identifying the best method for linearizing the nonlinear friction term to analyze the transient flow in pipeline systems [PDF]
Journal of Applied Research in Water and Wastewater, 2022 To analyze transient flows, continuity and momentum equations must be solved. Due to the non-linear friction term in the momentum equation, numerical methods such as method of characteristics (MOC) are used to analyze the problem in thetime domain ...

Manufacturing an Exact Solution for 2D Thermochemical Mantle Convection Models
Geochemistry, Geophysics, Geosystems, 2023 In this study, we manufacture an exact solution for a set of 2D thermochemical mantle convection problems. The derivation begins with the specification of a stream function corresponding to a non‐stationary velocity field.
