Title          
2D CFD Bullet in a Pipe 
   
 
Abstract    
This is not my video. I found it on the web. Thought it would be interesting to the community. This is a 2d CFD simulation of a supersonic bullet fired down a pipe, made using a special version of VH1 that can simulate flow around rigid objects.The solver is PPM-LR, piecewise-parabolic method (Collela & Woodward), with a Lagrangian remap.

Title          
Flow Visualization: Aerodynamics of Truck vs.... 
   
 
Abstract    

A video showing the flow of dye over and through a Nascar and Truck illustrating fluid mechanics and aerodynamics. In fluid dynamics it is critically important to see the patterns produced by flowing fluids, in order to understand them. We can appreciate this on several levels: Most fluids (air, water, etc.) are transparent, thus their flow patterns are invisible to us without some special methods to make them visible.On another level, we know the governing equations of fluid motion (the Navier-Stokes equations), but they are nonlinear partial differential equations with very few general solutions of practical utility. We can solve them numerically with modern computer methods, but these solutions may not correspond to ...

Title          
The Beauty of Chaos 
   
 
Abstract    
Mathematically, chaos means an aperiodic deterministic behavior which is very sensitive to its initial conditions, i.e., infinitesimal perturbations of boundary conditions for a chaotic dynamic system originate finite variations of the orbit in the phase space.

In lay terms chaotic systems are systems that look random but aren't. They're actually deterministic (predictable if you have enough information) systems that are governed by non-linear dynamics.

Title          
Surviving an Earthquake 
   
 
Abstract    
South West England might not be the first place you'd think to look for advice on surviving an earthquake -- but scientists at the University of Bristol, with complementary studies from the neighbouring University of the West of England, are at the cutting edge of research that explores and develops the basic principles used to protect structures during earthquakes
Earthquake damage worldwide is estimated to cost in excess of US$ 70 Billion a year - and this is without factoring in the inevitable loss of human life.
The University of Bristol will soon open its new BLADE laboratory (Bristol Laboratory for Advanced Dynamics Engineering) -- one of the world's largest facilities for simulating earthquakes, allowing testing and evaluation to improve the structure and construction of buildings in areas at risk; avoiding human suffering and the massive economic loss associated with earthquake damage.

Circular bubbles produced by Whales and Dolph... 
   
 
Abstract    
Circular bubbles produced by Whales and Dolphins. A bubble ring is an underwater ring vortex where an air bubble occupies the core of the vortex, forming a ring shape. The ring of air as well as the nearby water spins poloidally as it travels through the water, much like a flexible bracelet might spin when it is rolled off a person's arm. Some scuba divers can create bubble rings by blowing air out of their mouth in a particular manner. Long bubble rings also can form spontaneously in turbulent water such as in heavy surf. Bubble rings and smoke rings are both forms of vortex rings, and are sometimes studied in the field of fluid dynamics. Dolphins and humpback whales have also been seen to create bubble rings. Dolphins sometimes create bubble rings on purpose, seemingly for amusement.

Title          
Inverted pendulum control 
   
 
Abstract    

An inverted pendulum is a pendulum which has its mass above its pivot point. It is often implemented with the pivot point mounted on a cart that can move horizontally and may be called a cart and pole. Whereas a normal pendulum is stable when hanging downwards, an inverted pendulum is inherently unstable, and must be actively balanced in order to remain upright, either by applying a torque at the pivot point or by moving the pivot point horizontally as part of a feedback system.

The inverted pendulum is a classic problem in dynamics and control theory and widely used as benchmark for testing control algorithms (PID controllers, neural networks,

Title          
Damped and Driven Oscillations - Resonance 
   
 
Abstract    

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples include a swinging pendulum and AC power. The term vibration is sometimes used more narrowly to mean a mechanical oscillation but sometimes is used to be synonymous with "oscillation." Oscillations occur not only in physical systems but also in biological systems and in human society.

The simplest mechanical oscillating system is a mass attached to a linear

Title          
IBM Research Computational Biology Center  
   
 
Abstract    

Computational biology is an interdisciplinary field that applies the techniques of computer science, applied mathematics and statistics to address biological problems. The main focus lies in the development of computational and statistical data analysis methods and in developing mathematical modeling and computational simulation techniques. By these means it addresses scientific research topics with their theoretical and experimental questions without a laboratory. It is connected to the following fields: (1) Computational biomodeling, a field concerned with building computer models of biological systems.(2)

Title          
Aerodynamics 
   
 
Abstract    
Aerodynamics (shaping of objects that affect the flow of air or gas) is a branch of fluid dynamics concerned with the study of forces generated on a body in a flow. The solution of an aerodynamic problem normally involves calculating for various properties of the flow, such as velocity, pressure, density, and temperature, as a function of space and time. Understanding the flow pattern makes it possible to calculate or approximate the forces and moments acting on bodies in the flow. The use of mathematical analysis, empirical approximation and wind tunnel experimentation form the scientific basis for heavier-than-air flight.


Airflow across an aircraft wing. A greater angle deflects air downwards at a geater angle to increase LiftAerodynamic problems can be classified in a number of ways. The flow environment defines the first classification criterion. External aerodynamics is the study of flow around solid objects of various shapes. Evaluating the lift and drag on an airplane, the shock waves that form in front of the nose of a rocket or the flow of air over a hard drive head are examples of external aerodynamics. Internal aerodynamics is the study of flow through passages in solid objects. For instance, intern...
