Optimizing Motor Thermal Models

2006 Record of Conference Papers - IEEE Industry Applications Society 53rd Annual Petroleum and Chemical Industry Conference, 2006
The thermal limitations of induction motors are specified by thermal limit curves that are plots of the limiting temperature of the rotor and stator in units of l2t. This paper discusses the thermal protection provided by rotor and stator thermal models defined by the thermal limit curves and supporting motor data.

Thermal resistance (Rth) enhancement by optimizing TO package thermal contact

2010 34th IEEE/CPMT International Electronic Manufacturing Technology Symposium (IEMT), 2009
The trend for package size shrinkage has created challenges to thermal performance while improving the cost performance. When TO package size shrink by minimizing the leadframe copper usage, challenges in package warpage and thermal contact become great.

Optimizing thermal energy storage operation

Solar Energy, 2015
Abstract Thermal energy storage systems are usually attached to solar power plants to extend their operation beyond sunshine periods. Solar heat collected during the day is divided between a power block and a properly-sized thermal energy storage system.

Multi Software Thermal Design Optimization

2020 26th International Workshop on Thermal Investigations of ICs and Systems (THERMINIC), 2020
System level thermal optimization of a multi-part thermal design tools is exercised, where a low heat source temperature on one part, modelled in one tool, conflicts with the low mass design objective of a heatsink, modelled in another simulation tool.

Optimizing global thermal coal shipments

Omega, 2017
Abstract Thermal coal is used to produce energy; with changing emissions standards and advents in renewable technology, the thermal coal market has seen significant transformation over the past decade. We develop a mixed-integer optimization problem that seeks to minimize shipment costs while meeting demand for thermal coal, and which respects ...

Multimodal optimization of thermal histories

Comptes Rendus de l'Académie des Sciences - Series IIA - Earth and Planetary Science, 1999
Practical optimization problems often require the location of multiple solutions. In this context, we present a model, based on a genetic algorithm (GA) for the optimization of thermal histories. Since in classical GA, the population of individuals converges over time to a single optimum, even within a multimodal domain, the proposed approach uses a ...

Simplified thermal modelling for optimal thermal control strategy of buildings

AIP Conference Proceedings
Today, control, automation, and supervisory systems are essential components of HVAC systems for the benefits they offer in managing and optimizing resources. This paper intends to explore the identification of an optimal thermal control strategy that is responsive to the outdoor temperature distribution, and it is respectful of the features of the sub-

Optimization of Thermal Food Processing

2015
The process that is delivered to a canned or packaged food not only inactivates the spoilage microorganisms, but also cooks the product to an acceptable texture. Canned foods, being convenience foods, are thermally processed to such a degree that they only require reheating prior to consumption.

THERMAL OPTIMIZATION OF PULTRUDED COMPOSITES

2017
This paper wants to find the optimal heat flux and the optimal processing speed in order to increase the production rate and to obtain a pultruded part with a minimum established degree of cure. We have applied an approach that links PSO-based algorithm and a CFD code to optimize a L-shaped pultruded composite.
