Structuring Emperical Methods For Reuse And Efficiency In Product Development Processes, Marshall Edwin Bare
Structuring Emperical Methods For Reuse And Efficiency In Product Development Processes, Marshall Edwin Bare
Theses and Dissertations
Product development requires that engineers have the ability to predict product performance. When product performance involves complex physics and natural phenomena, mathematical models are often insufficient to provide accurate predictions. Engineering companies compensate for this deficiency by testing prototypes to obtain empirical data that can be used in place of predictive models. The purpose of this work is to provide techniques and methods for efficient use of empirical methods in product development processes. Empirical methods involve the design and creation of prototype hardware and the testing of that hardware in controlled environments. Empirical methods represent a complete product development sub-cycle …
Black Liquor Droplet Combustion And Modeling, Warren Benjamin Roberts
Black Liquor Droplet Combustion And Modeling, Warren Benjamin Roberts
Theses and Dissertations
Black liquor is an intermediate product of pulp production. Recovery boilers process black liquor to recover the inorganic material for recycling in the mill and to generate electricity and steam for the paper mill. Black liquor droplet combustion rates and mechanisms dictate many aspects of recovery boiler performance. This investigation documents new experimental data on single droplet pyrolysis and combustion in a laboratory furnace that mimics many of the essential features of commercial boilers (temperature, composition, droplet size, etc.). These experiments monitored single droplets placed on a thermocouple wire and suspended from a mass balance. Simultaneous video images and pyrometry …
