a transient 3 d inverse problem in imaging the time dependent local heat transfer coefficients for plate fin
Applied Thermal Engineering, 2005Co-Authors: Cheng-hung Huang, Yao Long TsaiAbstract:The local time-dependent surface heat transfer coefficients for plate finned-tube heat exchangers are estimated in a three-dimensional inverse heat conduction problem. The inverse algorithm utilizing the steepest descent method (SDM) and a general purpose Commercial Code CFX4.4 is applied successfully in this study in accordance with the simulated measured temperature distributions on fin surface by infrared thermography. Two different heat transfer coefficients for staggered as well as in-line tube arrangements with different measurement errors are determined. Results of the numerical simulation show that the reliable estimated heat transfer coefficients can be obtained by using the present inverse algorithm.

a three dimensional inverse problem in imaging the local heat transfer coefficients for plate finned tube heat exchangers
International Journal of Heat and Mass Transfer, 2003Co-Authors: Cheng-hung Huang, I-cha Yuan, Herchang AyAbstract:Abstract A three-dimensional inverse heat conduction problem in imaging the local heat transfer coefficients for plate finned-tube heat exchangers utilizing the steepest descent method and a general purpose Commercial Code CFX4.4 is applied successfully in the present study based on the simulated measured temperature distributions on fin surface by infrared thermography. It is assumed that no prior information is available on the functional form of the unknown local heat transfer coefficients in the present study. Thus, it can be classified as function estimation for the inverse calculations. Two different heat transfer coefficients for in-line tube arrangements with different measurement errors are to be estimated. Results show that the present algorithm can obtain the reliable estimated heat transfer coefficients.

simulation of the compaction process of a two level powder metallurgical part
Journal of Materials Processing Technology, 2003Co-Authors: A Bejarano, M D Riera, Jose Manuel PradoAbstract:Abstract In this work, a plasticity model for granular materials, based on the Drucker–Prager/CAP model, is applied to represent the behaviour of the metallic powders during their cold die compaction. The elastic deformation has been simulated by means of a non-linear law. These constitutive equations have been implemented in a Commercial Code to simulate the compaction and ejection processes of a two-level powder metallurgical part.

too clever by half reflections on perception legitimacy and choice of law under revised article 1 of the uniform Commercial Code
Social Science Research Network, 2015Co-Authors: Mark Edwin BurgeAbstract:The overwhelmingly successful 2001 rewrite of Article 1 of the Uniform Commercial Code was accompanied by an overwhelming failure: proposed section 1-301 on contractual choice of law. As originally sent to the states, section 1-301 would have allowed non-consumer parties to a contract to select a governing law that bore no relation to their transaction. Proponents justifiably contended that such autonomy was consistent with emerging international norms and with the nature of contracts creating voluntary private obligations. Despite such arguments, the original version of section 1-301 was resoundingly rejected, gaining zero adoptions by the states before its withdrawal in 2008. This article contends that this political failure within the simultaneous success of Revised Article 1 was due in significant part to proposed section 1-301 invoking a negative visceral reaction from its American audience. This reaction occurred, not because of state or national parochialism, but because the concept of unbounded choice of law violated cultural symbols and myths about the nature of law. The American social and legal culture aspires to the ideal that “no one is above the law” and the related ideal of maintaining “a government of laws, and not of men.” Proposed section 1-301 transgressed those ideals by taking something labeled as “law” and turning on its head the expected norm of general applicability. Future proponents of law reform arising from internationalization would do well to consider the role of symbolic ideals in their targeted jurisdictions. While proposed section 1-301 made much practical sense, it failed in part because it did not — to an American audience — make sense in theory.
