Investigation of second grade fluid through temperature dependent thermal conductivity and non-Fourier heat flux

open access: yesResults in Physics, 2018
Here we investigated stagnation point flow of second grade fluid over a stretchable cylinder. Heat transfer is characterized by non-Fourier law of heat flux and thermal stratification.

The inflow in the Baltic Proper as recorded in January–February 2015

open access: yesOceanologia, 2016
Inflowing saline waters of the Major Baltic Inflow (MBI) in 2014 were recorded in the Baltic Proper in January 2015. After 12 years of stagnation, this inflow brought highly saline (about 20) waters into the Bornholm Basin.

Temperature measurement in the flowing medium

open access: yesMATEC Web of Conferences, 2018
The article deals with a brief description of methods of temperature measurements in a flowing water steam. Attention is paid to the measurement of pseudo static temperature by a single sealed thermocouple entering the flowing liquid through the flown-by

Integrated production scheduling method to reduce fuel costs of hot rolling Processes

open access: yesNihon Kikai Gakkai ronbunshu, 2021
In order to minimize the fuel cost for heating steel ingots in hot rolling process, it is important to plan (1) batch formation to increase filling rate in furnaces and (2) work schedule to reduce stagnation of ingots in furnaces.

Effect of the stagnation temperature on the normal shock wave

open access: yesJournal of Computational Methods in Sciences and Engineering, 2009
When the stagnation temperature increases, the specific heat does not remain constant and start to vary with this temperature. The gas is perfect; its state equation remains always valid, except, it was called by calorically imperfect gas or gas at high temperature.
