Flow Dynamics and Heat Transfer
Ein Kapitel aus dem Buch Flow Dynamics and Heat Transfer

Abstract

Compressible fluid flow and heat transfer represent critical areas in fluid dynamics, particularly in applications involving high-speed aerodynamics, energy systems, and industrial processes. Thus, the exploration of the fundamental principles governing compressible flows, highlighting key phenomena such as shock wavesshock waves, expansion fans, and boundary layerboundary layer behavior, is the goal of this study. A comprehensive overview of governing equations, including the Navier-Stokes equationsNavier-Stokes equations and the energy equation, provides the foundation for understanding flow characteristics in compressible regimes. Modeling techniques specific to compressible flows are discussed, with emphasis on numerical methods such as finite volume and finite element approaches. Various simulation strategies are detailed, including steady-state and unsteady-state analyses, which are essential for predicting complex flow behaviors under varying conditions. Case studies illustrating practical applications, such as gas turbine performance and high-speed vehicle aerodynamics, demonstrate the significance of accurate modeling and simulation in optimizing design and efficiency. Challenges in simulating compressible flows, including numerical stability and turbulence modeling, are addressed, alongside advancements in computational capabilities, which enhance the accuracy of predictions. Furthermore, the interplay between flow dynamics and heat transfer is examined, emphasizing the role of temperature gradients in influencing fluid properties and system performance. As industries increasingly demand efficient thermal managementthermal management in compressible systems, understanding these dynamics becomes imperative.
