On Topological Approaches for Planning of Electro-Mechanical Assemblies
Assembly planning pertains to the process of creating a complete plan for fabricating the product from its constituent parts, considering the final product geometry and resources available at the manufacturing facility. ... -
One-domain simulation of fluid flow and heat transfer in the conjugate porous-clear media
In this thesis, based on generalized porous flow model, we present a one-domain framework for the simulation of incompressible flow in superposed clear and porous media. The continuous change in the characteristics of the ... -
Optimal Synthesis of Adjustable Four-Link Planar and Spherical Crank-Rocker Type Mechanisms for Approximate Multi-Path Generation
(2018-04-02)The well known synthesis problem of obtaining dimensions of a four-link mechanism such that a point on the coupler link traces a desired path has been extensively studied. There are two types of path generation–path specified ... -
Particle-laden Rayleigh-Benard convection
Particle-laden flows are ubiquitous in nature and industries. For example, water droplets in clouds, fine dust particles in strong winds leading to dusty storms, dunes, ejection of solid particles and ash during volcanic ... -
Passive Interfacial Evaporation-based Thermal Desalination Systems
Desalination offers a promising solution to the global water shortage by utilizing the vast resource of seawater. With 26% of the world’s population lacking access to potable water currently, there is a growing need to ... -
