Verification and Validation of the Caelus Library: Incompressible Flow Solvers

Emphasis of this paper is on the validation and verification of the open source numerical library, Caelus, suitable for the simulation of problems in continuum physics. The focus of this work is the verification and validation of problems in fluid mechanics. Several test cases including Couette and Kovasznay flows are used in verification of the steady state solver for incompressible flows. In addition, flat plate boundary layer, flow through a tee-junction and triangular lid-driven cavity are used in the validation part of the work. In all cases excellent agreement was found between the numerical, analytical and experimental results.
