To calculate the mean strain function, the residence time
and the strain rate history of the fluid elements shall be obtained, and it can be accomplished by particle trajectory method [6, 35], For this purpose, N inert particles are distributed evenly in the flow inlet, and the location of each particle in the channel is estimated by integrating the velocity over time as follows :
First, total residence time
for reaction is typically limited to the 1 to 3 minute range due to restrictions on machine length, as well as process economics.
In this article, the oil shale sample from Yaojie of Gansu province was pyrolyzed in an aluminum or iron retort to investigate influential factors, such as pyrolysis temperature, heating rate, residence time
and particle size.
Micro extruders allow for a short residence time
in the barrel, which helps to minimise thermal degradation especially compared to traditional size extruders running at very low screw speeds.
The material subjected to longer residence time
in the feed frame resulted in tablets that presented a slower dissolution of folic acid while the tablets from the low residence time
had faster dissolution.
Using radiocarbon dating, Valier Galy and Timothy Eglinton found that organic carbon resides in the basin for anywhere from 500 to 17,000 years, and that downstream, in the Gangetic floodplain, the longest residence times
range from 1,500 to 3,500 years.
The feed rate was varied in a way so that residence time
in TFR can be changed from 5 sec to 50 sec.
Factors influencing web site residence time
of the orb-weaving spider, Micrathena gracilis.
Whatever the application, the low quantity of product in the Turbulizer and short residence time
provide efficient use of installed power.
One shows that rivers or lakes are not really so unlike the Earth's mantle or a volcano, when viewed in terms of residence times
Each of these degass chamber volumes was designed to provide a minimum residence time
of 3 min.
Because residence time
is intrinsically controlled in segmented-flow processing systems, the heat transfer model can be used to determine microbial lethality.
