This portfolio presents a collection of high-fidelity CFD studies that reproduce experimental results with engineering accuracy. Each case is based on well-documented benchmark data, offering full transparency from geometry and meshing to solver setup and turbulence modeling. Because professional R&D projects often involve confidential work, these studies focus on publicly available experiments where every detail can be shared and verified. Together, they demonstrate what defines reliable CFD—physically consistent modeling, validation against experiments, and clear engineering reasoning—using Ansys Fluent in an open, traceable format comparable to industrial practice.
