What are the three types of heat transfer? What direction does heat flow? What is insolation in climatology? What is the study of natural philosophy? What is an enthalpy sensor? What is exercise science? What is a thermal engine? What type of scientist studies the cryosphere?
There is increasing need, in applications, for heat transfer descriptors which can deal with non-uniform thermal boundary conditions, including those induced by conjugate effects. This paper discusses two approaches which have arisen within the past 10 years: (1) the use of h...
About the '60 s, because of the space technology and the rapid development of advanced science, an urgent need to all kinds of high performance of compact heat exchangers, coupled with the stamping, brazing and seal the development of technology, such as heat exchanger manufacturing technology fu...
The Science of Thermodynamics Before embarking on a discussion of heat capacity and specific heat, it is useful to first understand the basics of heat transfer in physics, and the concept of heat in general, and familiarize yourself with some of the fundamental equations of the discipline. ...
Ketosis is a metabolic state in which the liver produces small organic molecules called ketone bodies at “sufficient” levels.
Does anyone know the heat transfer coefficient (&lambda in W K^-1 m^-1) of oil. I'm looking for this for polyolester, but if you have data of another oil, tha't would be fine! Thanks, Smurfje Science news on Phys.org Research team improves fuel cell durability with fatigue-resis...
This is the starting point for the below, Feynman being prescient again, but a masterclass.POINT: We know what to do and have come close to understanding much of nature in the last 200 years. In particular the last 20 years when most of the pseudo science of the Agenda 21 movement has...
