Each chapter has been contributed by the practiced experts in the field of fluid dynamics. This material covers a wide spectrum of CFD applications involving flow modeling in sedimentation tank, greenhouse environment, hypersonic aerodynamics, computational scheme, cooling systems design, photochemical reaction engineering, atmospheric reentry problem, fluid‐ structure interaction (FSI), atomization, hydraulic component design, air conditioning system, and industrial applications of CFD.
