11 Research Projects Natural convection in microelectronic enclosures Analytical modeling of heat sinks plate fin and circular annular heat sinks optimization routines Modeling of low Reynolds number flow heat exchangers Spreading resistance models sphere-layered substrate elastic contact circular & rectangular sources on compound disks and flux channels Characterization and modelling of thermal interface materials
12 Natural Convection in Enclosures Overview Develop analytical models for steady-state natural convection from a heated body to its surrounding, cooled enclosure Combine conduction and laminar natural convection limiting cases using composite solution technique Objectives Simple model formulation can include radiation and Develop analytical models for conduction effects steady-state natural convection from a heated body to its surrounding, cooled enclosure
13 Heat Sinks: Plate Fins Objectives develop a natural convection model for plate fin heat sinks with isothermal or isoflux boundary conditions Overview the heat sink geometry is specified using 6 geometric parameters, including fin spacing and thickness, base plate thickness, fin height and length and the total number of fins the heat sink is divided into two distinct regions: inner region - combination of boundary layer and fully developed flow outer region - combination of low Rayleigh flow conduction and boundary layer flow
14 Heat Sinks: Radial Fins Objectives develop a natural convection model for radial fin heat sinks with isothermal or isoflux boundary conditions Overview the heat sink geometry is specified using 5 geometric parameters, including inner and outer diameters, fin thickness and spacing and the total number of fins Publications Wang, C.S., Yovanovich, M.M. and Culham, J.R., 1999 General Model for Natural Convection: Application to Annular-Fin Heat Sinks, ASME Journal of Electronic Packaging, Vol. 121, No. 1, pp
15 Heat Sinks: Optimization Routines Objectives develop a thermal simulation tool that optimizes heat sink design variables based on the minimization of entropy generation establish a thermodynamic balance between heat transfer, viscous dissipation and mass transport Overview entropy production amount of energy degraded to a form unavailable for work lost work is an additional amount of heat that could have been extracted minimizing the production of entropy provides a concurrent optimization of all design variables
16 Modeling of Low Reynolds Flow Heat Exchangers Overview Objectives Develop analytical models for predicting the heat transfer and fluid friction characteristics for parallel and transverse flow through Offset Strip Fin (OSF) arrays. General models for predicting friction factors and Nusselt numbers for fully developed, thermally developing, and simultaneously developing flow in non-circular ducts. General models for predicting the friction factor and Colburn factor in Offset Strip Fin arrays for parallel and transverse flow. Models are developed by combining the asymptotic behavior for various flow regions.
17 Thermal Constriction Resistance: Sphere-Layered Substrate in Elastic Contact Objectives Develop a thermo-mechanical model for computing the constriction resistance of a sphere in elastic contact with a flat coated by metallic or nonmetallic (elastomer) layer. Overview Model can be applied to any combination of layer-substrate materials, including nonmetallics (for example silicon rubber). Publications Mirko Stevanovic and M.M. Yovanovich, 1999, "Modeling Thermal Constriction Resistance of Sphere - Layered Substrate in Elastic Contact", 37th AIAA Aerospace Science Meeting and Exhibit, January 1999, Reno Hilton, Reno, Nevada.
18 Thermal Constriction Resistance: Compound Disks and Flux Channels Objectives Develop analytical algorithms for calculating the spreading resistance from an isoflux source to a two-layer flux channel with convective or conductive boundaries. Overview A separation of variables approach is used to calculated the spreading resistance from planar heat sources of arbitrary dimensions to a compound heat flux channel. Limiting cases are examined for circular, rectangular and strip sources to finite, compound channels, half spaces and semi-infinite flux tubes
