A DOS-Enhanced Numerical Simulation of Heat Transfer and Fluid Flow Through an Array of Offset Fins with Conjugate Heating in the Bounding Solid
  E.M. Sparrow, J.P. Abraham, P.W. Chevalier
  "The method of Design of Simulation (DOS) was used to guide and enhance a numerical simulation of fluid flow and heat transfer through offset-fin arrays which form the interior geometry of a cold plate. The basic problem involved 11 independent parameters. This prohibitive parametric burden was lessened by the creative use of nondimensionalization that was brought to fruition by a special transformation of the boundary conditions. Subsequent to the reduction of the number of parameters, the DOS method was employed to limit the number of simulation runs while maintaining an accurate representation of the parameter space. The DOS method also provided excellent correlations of both the dimensionless heat transfer and pressure drop results. The results were evaluated with respect to the Colburn Analogy for heat and momentum transfer. It was found that the offseting of the fins created a larger increase in the friction factor than that which was realized for the dimensionless heat transfer coefficient."

A Finite Element Model For Pre- And Post-Test Calculations of the FOREVER-Experiments
  H. G. Willschuetz, E. Altstadt, F. P. Weiss, B. R. Sehgal
  "An axis-symmetric Finite Element (FE) model is developed based on the multi-purpose code ANSYS/Multiphysics. Using the Computational Fluid Dynamics (CFD) module the temperature field within the melt pool and within the vessel wall is evaluated. The transient structural mechanical calculations are then performed applying a creep model which takes into account large temperature, stress and strain variations." (Document 2)

Design and Implementation of a Flow Microsensor by using Silicon Microelectronics Technology
  Roberto Rodrigues and Rogerio Furlan
  "This work presents the design of a gas flow microsensor that was implemented by using silicon microelectronics technology. Its main features are a low power consumption (tens of mW) and the possibility of integration in flow microactuators. It was adopted a calorimetric device with free-standing microfilaments and thermoresistive sensor elements. Analytical and numerical modeling were developed for device analyses and design. The free-standing microfilaments were fabricated using surface micromachining. Characteristic curves, of output voltage vs. flow, were obtained by using a commercial flow sensor for calibration. A good agreement was obtained comparing the flow microsensor experimental characteristic curves with numerical simulation results."

The Control Of The Thermal Environment Of Perimeter Spaces In Buildings To Prevent Cold Drafts
  Yuji Hukushima, Yasuo Utsumi, Hiroshi Kobayashi, Yoshimi Ishikawa, Mitsuo Suzuki, And Tatsuya Yamash
  "This paper is focused on the evaluation of simulation system using the experiment result and the configuration of pericounter which is the part of counter unit setting at bottom of window side with heat panel to avoid the influence of cold draft, utilizing simulation system. The simulation shows similar flow pattern to full scale experiment and consequent simulations indicate that cold draft does not flow into interior zone when the heat generation rate exceeds heat loss from the window in most cases. When the heat generation portion is 75% of heat loss from the window, some cases which have certain configuration of pericounter successfully avoids the influence of draft without fan."

Three Dimensional Turbulent-Incompressible Fluid Flow Analysis Of A Ranger QCT Control Valve
  Joseph W. Smith, Keith Black
  "Cashco, Inc., desired to determine whether or not a Computational Fluid Dynamic (CFD) model could accurately predict the fluid flow through a Ranger QCT Control Valve. ANSYS Revision 5.4 was used to create the finite element mesh, apply loads, solve, and evaluate the results of the fluid analysis. The results of the fluid analysis showed that ANSYS predicted the Flow Coefficient and Pressure Recovery Factor to within 10% and 2% of their experimental values, respectively."

Transient Thermal Analysis of Spot Welding Electrodes
  K. S. Yeung, P. H. Thornton
  "The accurate thermal simulation of a spot welding electrode cap could permit critical design parameters to be identified for improved electrode life. In this study, a parametric model has been developed to predict the transient thermal behavior of a typical spot welding electrode cap. The model employs the technique of conjugate heat transfer analysis to avoid the problem of estimating a value for the heat transfer coefficient that arises with conventional heat transfer analysis."

TV Panel Glass Forming and Annealing Process Model
  John Chumley
  "This article describes the modeling technique used in forming a TV glass panel from the formation of the droplet of molten glass (gob) delivered to the forming machine (ELP) through the pressing and cooling operations plus the annealing oven (lehr). To assure the continuity of the solution, the model also tracks the return of the empty mold parts to their initial position on the ELP. The complexity of the problem and variety of solution domains involved requires multiple solution techniques."
