Hypothesis In droplet microfluidics applications, flow control and mixing in a small volume without any active external devices is a challenge. Vapor-mediated solutal Marangoni flows can be effectively generated by applying the vapor of a volatile li

Two side-by-side inverted flags in a uniform flow were simulated using the immersed boundary method. An energy harvesting system consisting of the two inverted flags was analyzed, and the flapping motions of the flags were investigated with considera

The schooling behavior of rigid and flexible NACA0017 airfoils undergoing a heaving motion was experimentally explored using a merry-go-round configuration. Each airfoil was attached to the end of a horizontal support bar whose other end was connecte

Flapping motions of wings and fins are common in nature. Living organisms use such motions to float in a fluid or to propel themselves forward. Some entities, such as tadpoles, use distinct flexible components to generate propulsion. Here we introduc

The steady, isothermal-fluidic field of forced moderator streams in a ¼ scaled moderator circulation tank (MCT) of a CANDU-6 reactor is analysed. Particular focus is placed on characterizing a secondary jet formed by the collision of symmetric, coun

An immersed boundary method (IBM) has been developed for the study of fluid-flexible body interactions with heat transfer. The fluid motion and temperature are defined on a fixed Eulerian grid, while the flexible body motion is defined on a moving La

A pair of flexible flags clamped vertically in a heated channel was numerically modeled to investigate the dynamics of the flexible flags and their effects on heat transfer enhancement. The penalty immersed boundary method was adopted to analyze the

Inducers assist cryogenic pumps to operate safely under cavitation conditions by increasing the pressure of the impeller inlet, but create cavitation instabilities. The use of cryogenic fluids requires special attention because of safety and handling
