Among the topics are wetting of surfaces: the contact angle, capillary interactions between particles: particles placed on liquid surfaces: the elasticity of liquid surfaces covered by colloidal particles, oscillation of droplets, the evaporation of droplets: the Kelvin effect and the coffee-stain effect, superhydrophobicity and superoleophobicity: the Wenzel and Cassie wetting regimes, and the
Leidenfrost effect: liquid marbles and self-propulsion.
One popular theory which is apparently accepted by mainstream science is the
Leidenfrost effect. According to this theory: For brief periods at high temperature, moisture from perspiration vaporizes into a protective layer of air to insulate the skin.
It proposes a new kind of engine for producing energy based on the
Leidenfrost effect - a phenomenon which happens when a liquid comes into near contact with a surface much hotter than its boiling point.
India, March 10 -- A team of researchers have developed a new technique based on the
Leidenfrost effect, which produces energy from carbon dioxide (CO2) that could be used to power space explorations and sustain life on Mars.
It proposes a new kind of engine for producing energy based on the
Leidenfrost effect -- a phenomenon which happens when a liquid comes into near contact with a surface much hotter than its boiling point.
Authors [7] proposed to reduce the drag force by using boiling crisis or
Leidenfrost effect. In 1756 year J.
Chemists have now exploited this phenomenon, known as the
Leidenfrost effect, to boil water without making bubbles (as seen at left, top).
Using a principle called the
Leidenfrost effect as a guide, the team was able to make water droplets stretch out on the hot surface of a steel ball covered in nanoparticles, rather than bubble.
