    Advanced Engineering Materials MECH 5623 February 14, 2017 SUPERFLUIDS Joshua Hobson Oklahoma Christian University, Graduate School of Engineering Edmond, OK ABSTRACT “Superfluids” are fluids that have zero viscosity. This means that the fluid will flow with zero friction as well as leak through certain surfaces that are otherwise considered sealed. In addition, superfluids are also superconductors. The paper discusses liquid helium, its discovery, properties applications and limitations. INTRODUCTION

    In this article, Kerson Huang explains what exactly dark matter and dark energy are, and their believed actions in the universe. He also discusses how space is a swimming pool of “superfluid,” and everything in the universe is floating in dark matter while being pushed by dark energy (Huang 1). If harnessed, any substance that has the power to move objects in space that are literally thousands of light-years across has the capacity

    liquid, gas, and plasma. Fortunately this is not true as that would be boring. There are also at least 4 other-less common states and Icontest a fifth. These are Bose-Einstein condensate, photonic molecules, quark-gluon plasma, superconductors, and superfluids. They all have unique properties that clearly distinguish differences between them and the traditional four states. These breakthroughs could help us in the future and have some practical uses right now. My personal favorite state of matter is

    States of matter are the distinct forms that different phases of matter take on. Historically, the distinction is made based on qualitative differences in bulk properties. Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter expands to occupy whatever volume is available. This diagram shows the nomenclature for the different phase transitions

    The world is made up of elements, from the iron in our blood, to the oxygen and carbon in the air. We use these elements everyday of our lives, even when we don’t realize it. But the one question that never crosses our mind is – Where do all the elements come from? Many may answer that these elements came from the Earth, but how did these elements end up on Earth? First, we have to look at the star cycle. Around 14 billion years ago, a giant nebula concentrated into a single tiny point, then proceeded

    At a temperature slightly above absolute zero, it is transformed into helium II, also called superfluid helium, a liquid with unique physical properties. It has no freezing point, and its viscosity is apparently zero; it passes readily through minute cracks. Helium-3, the lighter helium isotope, which has an even lower boiling point than ordinary

    Mechanics of Fluids and the Rayleigh-Bénard Problem 1 Introduction The motion of fluids in certain systems continues to be a relevant to physicists. From the coiling of dribbling fluids to the convection current of a slice of fluid heated from below, patterns forming in natural systems are still unsolved. The best that can be done is to make models of the systems and use approximations. In this paper I will give an overview of the Rayleigh-Bénard problem as well as describe the derivation

    superconductor at temperatures below -450 degrees Fahrenheit. From my physics class, I knew that superconductors were things that had no resistance and conducted electricity the best. What surprised me was the fact was that helium was the first superfluid to be discovered and that when it was present at such low temperatures, it lost all viscosity and could defy gravity by flowing uphill and over walls, which at times is still confusing. My third favorite compound that was created was the combination

    The 20th Century marked a revitalization of mathematics. Mathematicians were becoming increasingly aware of the shaky foundation that the mathematics of the time was built upon. Algebra seemed to change the most by this new move to fix the fundamentals of mathematics. With the intent to reinvent algebra, a group of young French mathematicians joined together under the pseudonym Nicolas Bourbaki. They collectively wrote a textbook named Elements of Mathematics. All the while, they held mathematical

    Properties of Fluids https://www.youtube.com/watch?v=Fe_f_mQCY6g Fluids have a variety of properties and with each property impacting how is flows around a medium. One of these properties of a fluid is viscosity. Viscosity is a property arising from friction between neighbouring particles in a fluid that are moving at different velocities. When the fluid is forced through a tube, the particles which comprise the fluid generally move faster near the tube’s axis and more slowly near its walls: therefore
