Non-uniform chip-temperature dependent signal integrity

2001 Symposium on VLSI Technology. Digest of Technical Papers (IEEE Cat. No.01 CH37184), 2002
In traditional design flows, the chip temperature is assumed to be uniform across the substrate. However, for most high-performance designs, the substrate temperature is nonuniform, which can be a major source of inaccuracy in delay and skew computations. This paper introduces the analysis and modeling of nonuniform substrate temperature and its effect

Silicon microcantilever hotplates with high temperature uniformity

Sensors and Actuators A: Physical, 2009
Abstract This paper presents microcantilevers with integrated heater–thermometers that are engineered to have regions of highly uniform temperature. The cantilevers are fabricated from doped single crystal silicon. Four cantilever designs are considered, where the regions of doping and the cantilever dimensions are selected to achieve the highest ...

Simulation investigation of heating rate and temperature uniformity in fluidized bed

, 2020
In this paper, the hydrodynamics and gas-solid heat transfer characteristics during bed material heating process are investigated using the CFD-DEM approach, and the heating rate and bed temperature uniformity are quantitatively analysed.

Temperature-driven self-assembly of self-limiting uniform supraparticles from non-uniform unimolecular micelles

Journal of Colloid and Interface Science, 2016
In this work, the self-assembly of non-uniform unimolecular micelles constituted of a hyperbranched polyester core decorated with a corona of thermoresponsive poly(N-isopropylacrylamide) (PNIPAm) chains has been studied. As revealed by dynamic light scattering (DLS), transmission electron microscopy (TEM) and small angle X-ray scattering (SAXS), these ...

Uniform Magnetic Fields and Equilibrium Flame Temperatures

Journal of Thermophysics and Heat Transfer, 2007
The impact of a constant uniform magnetic field on equilibrium flame temperature under constant volume conditions was examined. The equilibrium combustion compositions were found using an expression for Helmholtz free energy that included a magnetic-field contribution.

Improving temperature uniformity of a lithium-ion battery by intermittent heating method in cold climate

International Journal of Heat and Mass Transfer, 2018
The charge-discharge performances of lithium-ion batteries in hybrid electric vehicles (HEVs) and pure electric vehicles (EVs) decline rapidly at low temperatures.

Temperature Uniformity in Heating-Up Processes

Journal of Fluids Engineering, 1946
Abstract The treatment of temperature-uniformity problems by the method first introduced by Paschkis is extended and enlarged. It is shown that uniformity calculations can be reduced to the solution of a simple trigonometric relation which can be readily solved and analyzed.

Bubble growth in non-uniform temperature fields

Chemical Engineering Science, 1971
Abstract A previous theoretical model for bubble growth in superheated liquids has been extended to non-uniform temperature fields. The growth rate has been assumed as controlled by heat transfer, surface tension, liquid inertia and non-equilibrium at the liquid—vapor interface.

Schemes and effects on improvement of temperature uniformity inside indirect cooling wine cabinet

Applied Thermal Engineering, 2019
The purpose of this study is to improve temperature uniformity in a wine cabinet. Four basic methods are proposed at first, i.e., using solid shelves to separate the cabinet into several chambers and sending cold air into each chamber; providing an cold ...

Application of Jets and Vortex Generators to Improve Air-Cooling and Temperature Uniformity in a Simple Battery Pack

Journal of Thermal Science and Engineering Apllications, 2018
In this paper, the problem of air cooling and temperature nonuniformity at the cell and pack level is addressed. Passive techniques are developed by integrating jet inlets and vortex generators (VGs) in a simple battery pack with the goal to achieve an
