Fluid Flow Operations

Chapter-1 Flow Past Immersed Bodies:

Introduction

The Situation where the solid is immersed in, and surrounded by, fluid is the subject of this chapter.

Flow Past Immersed Bodies

There are 3 possibilities for flow past immersed bodies:

  1. Fluid at rest and the solid moving through it

2. The solid at rest and the fluid flowing past it

3. Fluid and the solid both moving.

The relative velocity between the fluid and solid is important.

Drag

The force in the direction of flow exerted by the fluid on the solid is called

drag. By Newton’s third law of motion, an equal and opposite net force is exerted by the body on the fluid.

When the wall of the body is parallel with the direction of flow, as in the case of the thin flat plate the only drag force is the wall shear τw.

Drag

However, the wall of an immersed body makes an angle with the direction of flow. Then the component of the wall shear in the direction of flow contributes to drag.

An extreme example is the drag of the flat plate perpendicular to the flow.

drag

The total drag on an element of area is the sum of the two components.

  1. The total integrated drag from wall shear is called Wall Drag.
  2. The total integrated drag from pressure is called Form Drag.
Drag Coefficients

Drag Coefficients

Drag coefficient is used for immersed solids.

Drag Coefficient for immersed solids

The drag coefficient,

  • You can understand the Dimensions Of The Evaporator from the image easily.
    Liquid Volume indicates the Minimum Amount Of Liquid you have to keep inside the
    Evaporator so that the Agitator Motor can give Maximum Efficiency For Heat Transfer
    with the help of an Anchor Agitator.
    In this example, you can select a motor with 3HP power and the range of rpm can be between 12 to 15
    rpm.
    You can buy all of this equipment from The Open Market, The Scrap Dealer, or you can
    Fabricate It Yourself if you have the resources and the manpower. motor to operate.

IMPORTANT SAFETY INSTRUCTION

While it is inspirational to start your own business, you should not forget to read our terms and conditions for your own safety. As you will be manufacturing your own system, we are not liable for any kind of mishaps and failures in your project. We strongly advise taking guidance from us or anyone else with proper knowledge and experience if you are new to the industry or feel even a little bit unsure about any aspect of your project. We hope that you make your decisions wisely.
