Steady-State Temperature rises of ONAN/ONAF/OFAF transformers
IEE Proceedings C Generation Transmission and Distribution, 1992Co-Authors: Z. Godec, R. SarunacAbstract:In the piping between the tank of a 40 MVA transformer, originally designed for ONAN/ONAF cooling combination, and its bank of radiators, a propeller oil pump was installed. Characteristic Temperature rises were measured before and after installation of the pump. The results were applied to the development of a new algorithm for calculation of windings and oil Steady-State Temperature rises of ONAN/ONAF/OFAF transformers. The mathematical model is briefly described in the paper, and the basic thermal characteristics of transformers with this combination of cooling types are described. Installation of the oil pump can make transformer cooling more efficient provided that certain conditions are satisfied.

An analytical solution to Steady-State Temperature distribution of N-layer viscoelastic suspensions used in crawler vehicles
International Journal of Heavy Vehicle Systems, 2012Co-Authors: Yong Song, Xin ZhangAbstract:An analytical method is proposed for solving the Steady-State Temperature distribution of N-layer viscoelastic suspensions with non-uniform heat generation. To find the Temperature distribution laws of the suspension, the heat flow and Temperature distribution formulas are derived. Two numerical examples are performed to verify the correction of the derived formulas. The Temperature results obtained by the derived formulas are compared with those obtained by Finite Element Method (FEM). The results show strong consistency with each other, which indicates that the proposed method is valid and feasible. The derived formulas can provide reference for the development of high performance N-layer viscoelastic suspensions.

A Solution to Steady-State Temperature Distribution for N-Combination-Layer Viscoelastic Suspensions with Nonuniform Heat Generation
International Journal for Computational Methods in Engineering Science and Mechanics, 2011Co-Authors: Yong Song, Xin ZhangAbstract:A method is proposed for solving the Steady-State Temperature distribution of N-combination-layer viscoelastic suspensions with nonuniform heat generation. The suspension's heat flow and Temperature distribution formulas are derived and their transformations are analyzed to demonstrate the validation in theory. Two numerical examples are performed to verify the correctness of the proposed method. The Temperature results obtained by the formulas are compared with those obtained by the finite element method (FEM). Strong consistency is shown between the results, which indicates the method is feasible. The proposed method can provide a reference for the development of high-performance N-combination-layer viscoelastic suspensions.

Physical characterization of Steady-State Temperature profiles in three-dimensional integrated circuits
2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015Co-Authors: Sumeet S. Kumar, Amir Zjajo, Rene Van LeukenAbstract:The thermal performance of three-dimensional integrated circuits is influenced by a number of design and technology parameters. However, the relationship between these parameters and thermal behaviour of die stacks is complex and not well understood. In this paper, we perform a detailed evaluation of the influence of stack composition and depth, thickness of dies, physical location of power dissipating elements and stack power density on Steady-State Temperature profiles. We examine how each of these parameters affects heat spread within 3D ICs, and highlight the causes for hotspot formation. The results of our analysis illustrate the implications of effective thermal conductivity on Temperature sensing zones on dies, and the significant impact of stack power density on overall operating Temperature.
