Fluid Mechanics Practice vs Pixel Wind Tunnel

Fluid Mechanics Practice is an educational application designed to help students understand and practice fundamental concepts related to fluid behavior at rest and in motion. The app focuses on practice-based learning through chapter-wise quizzes, mock tests, and daily quizzes aligned with standard Fluid Mechanics curricula. Users can practice questions from individual chapters, attempt mock tests for overall assessment, and monitor their performance using statistics. The app supports self-study, classroom learning, and exam preparation for engineering students. Topics Included 1. Basic Properties of Fluids Fluid mechanics fundamentals, density, specific weight, specific gravity, viscosity, and surface tension. 2. Fluid Statics Fluid pressure, pressure variation with depth, Pascal’s law, hydrostatic force, center of pressure, and manometers. 3. Fluid Kinematics Flow description, types of flow, streamlines, pathlines, streaklines, and velocity field. 4. Fluid Dynamics Newton’s law of viscosity, continuity equation, Bernoulli’s equation, momentum equation, energy losses, and applications. 5. Dimensional Analysis and Similitude Dimensions, dimensional homogeneity, Buckingham Pi theorem, Reynolds number, Froude number, and model analysis. 6. Flow Through Pipes Laminar and turbulent flow, Reynolds experiment, Darcy–Weisbach equation, minor losses, and pipe networks. 7. Boundary Layer Theory Boundary layer concepts, thickness, laminar and turbulent boundary layers, separation, and drag force. 8. Flow Measurement Venturimeter, orifice meter, pitot tube, weirs, notches, and discharge coefficient. 9. Open Channel Flow Open channel flow, flow classifications, specific energy, hydraulic jump, Chezy formula, and Manning’s equation. 10. Fluid Machinery Fluid machines, turbines, pumps, efficiency, specific speed, and engineering applications. Key Features Chapter-wise practice quizzes Mock tests for comprehensive assessment Daily quiz for regular practice Performance statistics to track progress Content aligned with Fluid Mechanics syllabus Simple and distraction-free interface Fluid Mechanics Practice is suitable for undergraduate engineering students preparing for examinations and strengthening conceptual understanding through consistent practice.

Draw a shape. Tap Simulate. Watch real fluid dynamics come alive in pixels. Pixel Wind Tunnel is a 2D fluid simulation app that runs real CFD (Computational Fluid Dynamics) calculations right on your device. No simplified approximations — the app solves the incompressible Navier-Stokes equations using the CIP advection method and Pressure Poisson solver, the same mathematical framework used in professional engineering software. HOW IT WORKS Draw any shape with your finger — airfoils, cars, buildings, anything Tap Simulate Watch the flow develop in real time That's it. Real fluid physics in three steps. SEE THE FLOW Switch between visualization modes to explore different aspects of the physics: • Velocity — where the flow speeds up and slows down • Pressure — high and low pressure regions around your shape • Vorticity — spinning structures and vortex shedding • Streamlines — paths that fluid particles follow MEASURE PERFORMANCE Real-time aerodynamic coefficients calculated from surface pressure and viscous stress integration: • Drag coefficient (Cd) • Lift coefficient (Cl) • Reynolds number Draw two different shapes and compare which one has less drag. Understand why streamlined shapes work better — with real numbers, not guesswork. EXPLORE DEEPER • Place point probes anywhere to track velocity and pressure over time • Scrub through simulation history with the timeline slider • Adjust inlet velocity and viscosity to change flow conditions • Save shapes with screenshots and reload them anytime REAL CALCULATION, NOT AN ANIMATION Every frame you see is computed from the actual Navier-Stokes equations. The CIP (Cubic Interpolated Propagation) method handles advection with minimal numerical diffusion, while the SOR iterative solver resolves the pressure field. Boundary conditions, viscous forces, and flow separation are all physically modeled. FOR CURIOUS MINDS Whether you're a student studying fluid mechanics, an engineer sketching quick ideas, a teacher demonstrating aerodynamics in class, or simply someone who wonders why things are shaped the way they are — draw it and find out.
