Experimental research of turbulent flow frequency spectra [PDF]

INCAS Bulletin, 2020
Hydraulic and heat transfer processes play a very important role in the design and prototyping of aerospace technology. In most cases this technique works under non-isothermal conditions.

Bi-quartic parametric polynomial minimal surfaces

, 2015
Minimal surfaces with isothermal parameters admitting B\'{e}zier representation were studied by Cosin and Monterde. They showed that, up to an affine transformation, the Enneper surface is the only bi-cubic isothermal minimal surface.

Austenite Formation Kinetics of Dual-Phase Steels: Insights from a Mixed-Control Model Under Different Heating Conditions

Modelling
A semi-analytical mixed-control model based on the Non-Partitioned Local Equilibrium (NPLE) assumption was developed to simulate the austenite phase transformation kinetics during heating and isothermal processes. The model was validated by comparing the

Non-isothermal model for the direct isotropic/smectic-A liquid crystalline transition

, 2009
An extension to a high-order model for the direct isotropic/smectic-A liquid crystalline phase transition was derived to take into account thermal effects including anisotropic thermal diffusion and latent heat of phase-ordering.

Mass-sheet degeneracy, power-law models and external convergence: Impact on the determination of the Hubble constant from gravitational lensing [PDF]

, 2013
The light travel time differences in strong gravitational lensing systems allows an independent determination of the Hubble constant. This method has been successfully applied to several lens systems.

Effects of austenizing temperature, cooling rate and isothermal temperature on overall phase transformation characteristics in high carbon steel

, 2020
Summary Phase transformations in high-carbon steel has been investigated by dilatometry during continuous cooling and isothermal transformations, following austenizing at temperatures of 900°C to 1200°C (1173 to 1473 K).

The role of ausforming in the stability of retained austenite in a medium-C carbide-free bainitic steel

Journal of Materials Research and Technology, 2020
In this work, the influence of thermomechanical treatments, consisting of a combination of ausforming followed by isothermal holding and cooling to room temperature, on the stability of retained austenite of a carbide-free medium carbon-high silicon ...
