What are heat and mass transfer?

Heat and mass transfer are commonly referred to as the processes by which an electric current (electromotive force) is applied to an external mechanical force and resulting heat is transferred from one body to another. A high voltage electrical circuit generates a low mechanical force. Heat transfer (also known as heat conduction) from a body to another is required to reach the object at a high temperature. The applied electrical voltage generates heat at the contact area between two material bodies. About the journal Published quarterly by Springer Nature, the journal features reviews, original papers, articles from leading scholars, conference abstracts, case studies and a dynamic communications area.

Fundamentals of fluid mechanics

The fundamental principle of fluid mechanics is that fluid motion is governed by mass conservation and pressure conservation, whereas surface friction provides a method of removing individual particles from fluid flow. This article provides a succinct outline of the diverse properties of fluids that we deal with in our everyday lives. To begin, we will briefly discuss the Navier-Stokes equation, which is considered the key analytical tool in fluid mechanics. The Navier-Stokes equation, which was introduced in 1807 by the French mathematician and physicist Émile Léonard de Villefière, explains how, at any given time, fluid flows over a surface in a manner that preserves the product of the speed of movement and the force of gravity.

Fundamentals of mass transfer

The conceptual science of mass transfer comprises mechanical, thermal and convective phenomena. These are used for convective cooling in low temperature systems, for heat transfer in large heat capacities and for cold plasmas. Generally, the physical phenomena of mass transfer can be divided into four main categories: static mass transfer, dynamic mass transfer, turbulent mass transfer and heat conduction. Dynamic mass transfer occurs in high temperatures, where fluid particles move through a medium and are influenced by the shear, capillary, radial and viscous forces. Sometimes, fluids at low temperature can also be considered as the solution to the equation of state of the fluid.

Conclusion

Time and time again we have found that funders are not looking for science-based results. Instead, they look for a “high impact” study. As we continue to see, money doesn’t determine research quality. In the pursuit of a high impact study, institutions like RPI rely on questionable science. Instead of working towards making a positive change in society, they are choosing to dig into relationships between race and blood test results. Is there a place for toxicology at RPI? Is there a need for true research that will improve the quality of life of the students? The answer is “No.” It’s time to bring real science back to the undergraduate science community. Let’s work towards producing results that are both well respected and effective.
