Separate effects of surface roughness, wettability and porosity on boiling heat transfer and critical heat flux and optimization of boiling surfaces
(Massachusetts Institute of Technology, 2012)
The separate effects of surface wettability, porosity, and roughness on critical heat flux (CHF) and heat transfer coefficient (HTC) were examined using carefully-engineered surfaces. All test surfaces were prepared on ...
Analysis of crowdfunding descriptions for technology projects
(Massachusetts Institute of Technology, 2013)
There are many factors that contribute to the success of a project on crowdfunding sites, such as Kickstarter. These include, but are not limited to, the specified project goal of funding, the success of similar projects, ...
Design and vibration testing of a flexible seal whisker model
(Massachusetts Institute of Technology, 2013)
Harbor seal whiskers have a unique surface structure that dramatically reduces vortex induced vibrations as they move through the water. Concurrently with rigid whisker experiments, this project focuses on the design and ...
Nuclear tanker producing liquid fuels from air and water
(Massachusetts Institute of Technology, 2011)
Emerging technologies in CO₂ air capture, high temperature electrolysis, microchannel catalytic conversion, and Generation IV reactor plant systems have the potential to create a shipboard liquid fuel production system ...
Construction of prototype system for directional solvent extraction desalination
(Massachusetts Institute of Technology, 2012)
Directional solvent extraction has been demonstrated as a low temperature, membrane free desalination process. This method dissolves the water into an inexpensive, benign directional solvent, rejects the contaminants, then ...
Parabolic trough solar collectors : design for increasing efficiency
(Massachusetts Institute of Technology, 2011)
Parabolic trough collectors are a low cost implementation of concentrated solar power technology that focuses incident sunlight onto a tube filled with a heat transfer fluid. The efficiency and cost of the parabolic trough ...
Analytic and numerical study of underwater implosion
(Massachusetts Institute of Technology, 2013)
Underwater implosion, the rapid collapse of a structure caused by external pressure, generates a pressure pulse in the surrounding water that is potentially damaging to adjacent structures or personnel. Understanding the ...
Evaluation and improvement of proactive customer notification in e-commerce environment
(Massachusetts Institute of Technology, 2005)
The Internet, and thus e-commerce, both Business to Consumer (B2C) and Business to Business (B2B), has changed the way companies do business with each other and communicate with their customers. Because of the speed of the ...
Managing forecast variability in a build-to-order environment
(Massachusetts Institute of Technology, 2007)
In any production environment, managing demand variability is a delicate balancing act. Firms must constantly weigh potential obsolescence costs of unused inventory (should sales not materialize) against potential expedite ...
Relationship of grain boundary structure and mechanical properties of Inconel 690
(Massachusetts Institute of Technology, 2009)
Stress corrosion cracking (SCC), failure due to environmentally assisted crack nucleation and propagation, is an important metallurgical problem with impact on current and future designs of ship structural components and ...
