Fluid Dynamics and Cosmology are widely separate disciplines. Problems like the flow of water through a pipe have little to do with evolution and fate of universe, but if fluids are to move near the speed of light, one will find some interesting properties that might have cosmological implications.
Affixing Fluid Dynamics and Cosmology, The Department of Mathematics SRMIST, Ramapuram organized three days International Virtual Workshop on “Mathematical Techniques in Fluid Dynamics” from 28th to 30th March 2022 for research scholars and faculty members.
Dean E&T in his felicitation address, appreciated the department for organizing the workshop on “Mathematical Techniques in Fluid Dynamics”
DAY -1
Date & Time:
28th March 2022
02.30 PM IST
Resource person:
Dr. Subrata Kumar Sahu
Associate Professor,
Department of Mathematics,
Arbaminch University, Ethiopia.
Topic: Wet Dark Fluid in F (R, T) Theory of Gravity
Dr. Subrata Kumar Sahu started the session with an introduction of Expanding Universe -consistent with a Big Bang and about Olber’s Paradox. He explained about Large Scale Structure of the Universe which are patterns of galaxies and matter on scales much larger than individual galaxies or groupings of galaxies and its relation to Dark Matter. He briefed on Hubble’s Law, cosmic microwave background which is leftover radiation from the Big Bang or the time when the universe began. He further spoke about the abundances of the elements in the universe, Matter, Energy density and the future of the universe, Life and Parallel Universes.
DAY – 2
Date & Time:
29th March 2022
02.00 PM IST
Session – 1
Resource Person:
Dr. Shumatir Yohannis
Department of Mathematics,
Arbaminch University, Ethiopia.
Topic: Significance of Fluid Dynamics in Science and Technology
Dr. Shumatir Yohannis started the session by describing about fluid dynamics as a branch of applied science that is concerned with movement of fluids and gases. He further discussed about the movement of blood flow in arteries and veins, Interfacial fluid dynamics, geological fluid mechanics, the dynamics of ocean, laminar-turbulent transition. He defined basic definitions of fluid, types of fluids, stresses, Newtons law of viscosity, Laminar flow Vs Turbulent flow. He detailed about classification of fluids – Compressible fluid, Incompressible Fluid, Newtonian fluid and non-Newtonian fluids.
Session – 2
Resource person:
Ms. Koye Gelgelo Guyola
Department of Mathematics,
Arbaminch University, Ethiopia.
Topic: Mathematical study of blood flow motion in an artery with the presence of magnetic field
Ms. Koye Gelgelo Guyola explained about motion of blood through an artery in the presence of magnetic field. She explained the mathematical modelling of blood flow motion using coupled non-linear ordinary differential equations and its analytical solutions. She further explained how the of blood flow motion is increased with increase in magnetic field and how body temperature can be maintained with the help of magnetic field.
DAY- 3
Date & Time:
30th March 2022
02.30 PM IST
Resource person:
Dr. Mergia Balcha Wakjira
Post Graduate Director,
Department of Mathematics,
Metropolitan University, Addis Ababa, Ethiopia.
Topic: String and Dark Fluid Cosmological Model
Dr. Mergia Balcha Wakjira started the session by explaining about dark fluid theory. He said dark fluid theory is an attempt to explain dark matter and dark energy in a single framework… At galactic scales, the dark fluid behaves like dark matter and at larger scales its behaviour becomes similar to dark energy. He further described about cosmic string – a hypothetical threadlike concentration of energy within the structure of space–time. The cosmic Microwave background radiation and large-scale structure of the universe is usually explained as Friedman-Robertson Walker (FRW) models with a cosmological constant. He further said cosmological models helps understand the early evolution of the universe.
The Three-Day International Virtual workshop concluded with vote of thanks proposed by Dr. Lalitha, Assistant Professor of Mathematics. More than 200 participants all over the world participated in this three-day international virtual workshop.
