Existing methods of drying fabrics involve energy-intensive thermal evaporation of moisture from clothes. Drying fabrics using high-frequency vibrations of piezoelectric transducers can substantially reduce drying time and energy consumption. In this method, vibrational energy generates instability on the liquid-air interface and mechanically ejects water from a wet fabric. Here, for the first time,...

This paper provides a summary of recent experimental work in electrohydrodynamic (EHD) conduction pumping of dielectric liquid, done by the authors and others in the Multi Scale Heat Transfer Laboratory at WPI. The primary objective of all experiments was to gain a fundamental understanding of interaction of flow fields and electrical fields in the presence and absence of phase change (liquid-vapor)...

Microscale heat transport devices driven by electrohydrodynamic (EHD) conduction pumping have been successfully developed over the last several years and can efficiently operate for short periods of time. The pumps are made up of specially designed electrodes, which generate an intense electric field and result in the flow of a dielectric liquid. The pumps are used upstream of an evaporator in a two-phase...

Research on heat transport in microscale has been generating much interest in the recent years due to the development of state-of-the-art high-powered electronics used in aerospace and terrestrial applications and the large amount of heat produced during their operation. Microscale two-phase-flow heat-transport devices are seen as one solution to this problem of high heat-flux removal. Microscale...

Fluid flow generation in micro-scale is becoming increasingly important as two-phase flow thermal management devices at the micro-scale are being widely developed. These devices are currently being used to cool high heat flux sources with small surface areas, found in various electronic, computer and aerospace applications. Limitations in space and power call for a simple yet effective flow generation...
