Inverse leidenfrost drop manipulation using menisci - Soft.

Dissertation Leidenfrost

The Leidenfrost pump design consists of a closed-channel with ratcheted sidewalls to propel the liquid. A key feature of the closed channel pump is a proposed concept for vapor removal. The vapor is extracted from the liquid channel to the surrounding atmosphere through separate variable-depth channels. The Marangoni pump design consists of an open-channel with a ratcheted bottom channel wall.

Electrostatic control and enhancement of film boiling heat.

Dissertation Leidenfrost

Here, we study this reflection in detail, and show that frictionless Leidenfrost drops are a simple and efficient tool to probe the shape of an unknown interface. We then use the menisci to control the motion of the otherwise elusive drops. We create waveguides to direct and accelerate them and use parabolic walls to reflect and focus them.

Abstract: The Leidenfrost effect influences substantially the contact of a liquid droplet with a hot surface. Contact between the liquid and solid is crucial for cooling applications such as fire-fighting, hot-mill steel rolling, thermal power plants and microprocessor cooling.

Numerical Modeling and Investigation of Boiling Phenomena.

Dissertation Leidenfrost

This dissertation is divided into five main studies, which analyze different aspects of electrostatic suppression of the Leidenfrost state. The first part of this dissertation (Chapter 2) describes droplet-based experimental investigations on electrostatic suppression of the Leidenfrost state. It is demonstrated that the Leidenfrost state can be suppressed and surface dryout can be prevented.

For instance, it can occur for a Leidenfrost droplet; a water drop levitating above a hot plate whose temperature is much higher than the boiling temperature. In this case, boiling occurs in the film of saturated vapor which is entrapped between the bottom of the drop and the plate, whereas the top of the water droplet evaporates in contact of ambient air. The situation can also be ambiguous.

In this thesis, the Leidenfrost drop has been introduced as a water-based green chemical reactor for simultaneous synthesis and self-organization of nanostructures. An important contribution of this work is in exploring the origin and mechanism of the nanofabrication at Leidenfrost condition. It turns out that these conditions are based upon overheated and charged nature of the droplet.

To investigate these puzzles, a Leidenfrost collider was constructed on which drops floating on a vapor layer were guided to merge and subsequently jump on a substrate heated well above the liquid boiling point. The jumping velocity upon symmetric coalescence of equally-sized drops was observed to follow the capillary-inertial scaling, and the non-dimensional jumping velocity of approximately.
