Towards a guided framework for innovative engineering through the generation and evaluation stages of concept design

Creator:: Oman, Sarah Kay
Abstract:: This work proposes a framework of concept generation and evaluation that takes into consideration the benefit of creativity and innovation in current market trends. By educating engineers in how to increase creativity in concept design and assess it quantitatively, the next generation of designers will be a step ahead of...

A study of thermal stratification in the cold legs during the subcooled blowdown phase of a loss of coolant accident in the OSU APEX Thermal Hydraulic Testing Facility

Creator:: Wachs, Daniel M.
Abstract:: The phenomena of interest in this work is the thermal stratification which occurs during the early stages of a loss of coolant accident (LOCA) in the OSU APEX Thermal Hydraulic Test Facility, which is a scaled model of the Westinghouse AP600 nuclear power plant. Thermal stratification has been linked to...

Resilient Design for Complex Engineered Systems in the Early Design Phase

Creator:: Keshavarzi, Elham
Abstract:: There are many uncertainties that complex engineered systems will face throughout their lifecycles due to changes in internal and external conditions. It is desirable for complex engineered systems to be resilient against various uncertainties. The ability to overcome such uncertainties should be embedded into the system from the beginning. However,...

The effect of geometric orientation and random wind conditions on flat plate convection rates

Creator:: Melchior, Daniel K.
Abstract:: An experimental investigation has been performed to determine the forced convection heat transfer due to three-dimensional air flow over a flat plate as a function of angle of attack and free stream velocity. The experimental method employed a transient thermal technique and placed the convecting surface next to the exhaust...

Natural convection from a horizontal cylinder parallel to a heated vertical wall

Creator:: McCoy, Timothy J.
Abstract:: Heat transfer measurements have been made from a long (L/D = 15) horizontal cylinder in water parallel to a heated vertical wall. The cylinder and wall boundary conditions were isothermal, and they were maintained at equal temperatures. The investigation covered Rayleigh numbers based on cylinder diameter from 400,000 to 10,000,000....

Achieving Transparency in Human-Collective Systems

Creator:: Roundtree, Karina A.
Abstract:: Collective robotic systems are biologically-inspired and exhibit behaviors found in spatial swarms (e.g., fish), colonies (e.g., ants), or a combination of both (e.g., bees). Collective robotic system popularity continues to increase due to their apparent global intelligence and emergent behaviors. Many applications can benefit from the incorporation of collectives, including...

An experimental investigation of natural convection heat transfer from an array of uniformly heated vertical cylinders to mercury

Creator:: Dutton, Jonathan Craig
Abstract:: An experimental investigation was conducted for natural convection heat transfer in an array of uniformly heated vertical cylinders in mercury. The test section consisted of seven electrically heated cylinders of 1.365 inch diameter and 3.825 inch heated length arranged in an equilateral triangular pattern. In order to preclude side flow...

An experimental study of natural convection heat transfer from a horizontal cylinder array vertically aligned to and confined by a single wall and two walls

Creator:: Al-Alusi, Thamir R.
Abstract:: Convection heat transfer was experimentally investigated for two different geometries. One case had three horizontal cylinders in a vertical plane placed between two vertical walls. The second case had three horizontal cylinders in a vertical plane with only one vertical wall. Several different cylinder center-tocenter spacings were investigated. The wall...
