Aerodynamic physics of the Delta Wing – POST #100

Reference: ResearchGate Delta wings are known as highly swept wings and that's what makes them aerodynamically more efficient at a high angle of attack. Supersonic aircraft are equipped with such wing configurations. The high-speed aircraft have to fly at low speed for takeoff and landing. Therefore it is important to study their aerodynamic characteristics at …

Volume of Fluid: Interface Capturing Method (Multiphase flow)

Reference: Slideshare Multiphase flow classification Multiphase flows have phase boundaries that have an inter-phase coupling with mass, momentum, and energy transfer between different phases. They can be classified into 2 categories based on phase interaction, Continuous-Continuous phase interaction & Dispersed-Continuous phase interaction.   Ocean Wave (Continuous-Continuous phase interaction) Bubble motion in Liquid (Continuous-Dispersed phase interaction) Continuous-Continuous …

From Reynolds Transport Theorem to Navier-Cauchy to Navier-Stokes Voyage: Part II

In part I of this blog, we have discussed the evolvement of the Conservation of Linear Momentum Equation from Newton's Second Law of Motion using the Reynolds Transport Theorem. During the process we covered what is the need for Reynolds Transport Theorem, The Forcing & Stress Tensor Concept in Fluid: Fluid Kinematics Perspective, derived Cauchy …

From Reynolds Transport Theorem to Navier-Cauchy to Navier-Stokes Voyage: Part I

There are certain fundamental principles of conservation that govern the implementation of CFD. These principles are Conservation of mass, momentum & energy. We will see how we can represent these principles evolve in a mathematical form that expresses the dynamics of fluid flow by preserving mass, momentum and energy conservation. The Need of Reynolds Transport …

SIMPLE Algorithm: Way to solve incompressible NV-Stokes Equation

Introduction Transport equations for each velocity component – momentum equations – can be derived from the general transport equation by replacing the variable φ with u, v and w respectively. The above equations govern a two-dimensional laminar steady flow. The Main Problem! The velocity field obtained from the momentum equation must also satisfy the continuity …
