Hello everybody. Welcome to this Massive Open
Online Course.
As you know that in our daily life, we are
using various products, byproducts even some
devices which are being used for our different
convenient to travel, even to design some
equipments.
You will see all those products, even byproducts
or those devices are very much related to
the fluid flow operations because all those
products are directly or indirectly is being
processed by a certain process and, or designed
a certain equipment which are related to this
fluid flow operations.
So to design or to know the basic of this
process based on this fluid flow operations,
you have to know some fundamentals of the
flow of the fluid, how it is actually related
to the process even in chemical engineering,
mechanical or civil engineering processes.
Some processes in the chemical processes you
will see that some products are being produced
in a particular process, that process is,
is being taken place in a certain equipment.
So in that case you will see that equipments
are being designed based on the fluid flow
operations.
Like one example here, if suppose if you are
going to remove the carbon dioxide from the
atmosphere, you have to supply this carbon
dioxide gas which are in atmosphere to a certain
processing unit.
In that case as an example suppose this gas
as carbon dioxide and air mixed gas is supplied
to a pool of liquid as it is first phase of
gas bubbles or carbon dioxide gas bubbles
where you will see that carbon dioxide gas
from the air is being transported to the liquid.
And in that case there is a operation, it
is called mass transfer. That means carbon
dioxide gas is being transported from the
gaseous phase to the liquid phase. So in that
case, from the atmosphere you can absorb or
remove the carbon dioxide and capture it into
a liquid.
And if there is a certain operation at a certain
temperature and pressure you can convert this
carbon dioxide gas to other products. So for
this you know that since this is a flow of
the gas in a liquid, sometimes say for continuous
operations you can supply the liquid in countercurrent
way, so in that case fluid flow is very interesting,
or important.
And in that case you have to know how that
fluid is flowing for that particular application
and what will be the effect of this fluid
flow and also some other characteristics of
the fluid. So this is one example for this
chemical engineering process.
Even there are several other processes which
we are using to produce our products which
are being used in our daily lives. Even in
civil engineering process if you are concerning
that there is a built of bridge. So in that
case whenever you are procuring any bridge
then you have to know the flow pattern of
the fluid which are being flowing upward in
the rivers or some other canals.
In that case how, what will be the flow pattern,
how, what will be the flow rate, all those
things to be actually taken care and also
there will be slurry systems in a particular
operation so in that case you have to know
for the, that is, that is, you know, sometimes
you know that muddy flow is there and for
certain operations that you have to know how
much actually flow rate is there.
So that particular process of that slurry
systems, even in some other chemical engineering
process in fluidized bed, there are slurry
flow. So in that case you have to know the
fluid flow phenomena of that particular operations.
Even in mechanical engineering you will see
if you are going to devise certain equipment
in automobile industries or some other cases,
in that case you have fluid flow phenomena
based on which, it is directly actually related
to that design here.
If you know the fluid flow phenomena in that
case then the design of that equipment that
you have to easily, actually understand how
it is being happened there. And the flow characteristics
of the device and what will be the capacity
of the device and how this fluid flow will
enhance or you know that affect the capacity
of these devices.
Like pump, whenever you are going to design
a pump, what should be the capacity that it
is actually related to the fluid flow operations,
so in that case you have to know the basic
fundamentals of the fluid flow operations.
So in this case the fluid flow operations,
the directly or indirectly related to the
flow, processes and that flow process will
give you our daily life products, even for
convenient way to how to use those devices
in that case.
And also in our, you know that biotechnology
process also sometimes, some bio-processes,
there these fluid flow operations are actually
important. So in that case what should be
the hydrodynamic aspect, that hydrodynamic
are related to that efficiency of the process.
So in that case you have to know these fundamental
of this fluid flow operations.
So this course I think, it is very useful
and it will be, I think beneficial for the
learner because this course is designed in
such a way that reader can easily understand
and it is made so easy so that they can easily
understand.
And after the course, you will get some assessment
also, and also assignment that will be given
to you and based on that assignment you can
assess yourself how much you actually can
understand these basic fundamentals of this
fluid flow phenomena.
And special attention is given here in this
lec/lecture, in this course we will discuss
or here some applications of the multiphase
flow phenomena because in our daily life,
the daily processes for our daily products
you will see that maximum processes are related
to the multiphase flow systems here, that
way gas-liquid, even liquid-solid, gas-liquid-solid,
those are called multiphase systems.
So all the processes are directly or indirectly
related to that multiphase processes. Some
examples of that multiflow, multiphase flow
process event, its phenomena will be discussed
and also some examples of these multiphase
flow phenomena will be also shown in this,
in the video in the lecture there.
So I think you will enjoy the course. After
getting this course you will be benefitted
for your further learning based on this basic
understanding of the fluid flow.
So I welcome all of you to learn this course.
So I am Subrata Majumder as a faculty, the
Chemical Engineering Department, I I T Guwahati.
So I welcome you to learn this course, thank
you.
