Heat transfer and thermal deformations in non-contacting face seals

open access: yesJournal of Thermal Science and Technology, 2014
The simulations conducted for non-contacting face seals show that performance-related parameters greatly affect the distribution of temperature in the fluid film causing thermal deformations of the sealing rings.

Numerical investigations on thermal deformation of large deployable reflector in space during earth eclipse (2nd report, investigations to suppress thermal deformation by internal force control)

open access: yesNihon Kikai Gakkai ronbunshu, 2016
Space structures encounter various severe environments in space. One of these environments is severe thermal condition where the difference of temperature during day-time and night-time is about 200 degrees Celsius. During this eclipse time, the midpoint

Thermal rectifiers from deformed carbon nanohorns [PDF]

open access: yesJournal of Physics: Condensed Matter, 2008
We study thermal rectification in single-walled carbon nanohorns (SWNHs) by using non-equilibrium molecular dynamics (MD) method. It is found that the horns with the bigger top angles show larger asymmetric heat transport due to the larger structural gradient distribution.

A Novel Thermal Deformation Self-Stabilization Flexible Connection Mechanism

open access: yesActuators
In micro-LED chip repair, a nanopositioner is commonly used to adjust the positioning of the LED chip. However, during the bonding process, the heat generated can cause the positioning system to deform, leading to inaccurate alignment and poor-quality ...

On the Thermal Deformation of Limit Gauge

open access: yesJournal of the Japan Society of Precision Engineering, 1952
In the mass production, limit gauges are generally used to measure the machine parts. The thermal deformation of gauge in use is changed by the time and the method of holding, which is researched here.With the 50 millimetre limit gauge, the maximum deformation after holding 30 minutes is about 4.0μ and this is nearly equal to the working tolerance of ...

Shift of dynamic recrystallization kinetics in thermal compression induced by prior cold deformation treatment at Ni80A superalloy

open access: yesJournal of Materials Research and Technology
To achieve the uniform and fine-grained microstructures during thermal deformation of nickel-based superalloys, a novel two-stage deformation approach was employed, involving prior cold deformation treatment (PCDT) and subsequent thermal deformation ...
