Water Drops on Surfaces

Water motion is a highly complex phenomenon. From ocean waves to raindrops, water is described by a wide range of shapes and is affected by a wide range of forces. This paper presents a physically-based method of modeling the latter phenomenon raindrops. This model can handle bodies of water with varying underlying terrain, as well as many different fluids, but cannot represent spray systems, w...

Water spring: a model for bouncing drops

– It has been shown that a water drop can bounce persistently, when thrown on a super-hydrophobic substrate. We present here scaling arguments which allow us to predict the maximal deformation and the contact time of the drop. This approach is completed by a model describing the flow inside the drop, and by original experimental data. Introduction. – A liquid ball is a drop which remains quasi-...

Intelligent Water Drops Algorithm for Multimodal Spaces

This paper presents a new nature inspired Intelligent Water Drops (IWD) based algorithm for finding peaks in continuous multimodal optimization problems. Initially various conceptual similarities were identified between IWD algorithm and Genetic Algorithm(GA). Simultaneously applying IWD-Continuous Optimization(IWD-CO) algorithm and GA on a function in finding the global optima and found IWDCO ...
