Uniform flow is a characteristic of ideal fluid behavior, where the fluid moves in a steady and consistent manner without any disturbances or variations in flow velocity or pressure. Ideal fluid assumes that the flow is frictionless, incompressible, and irrotational, which allows for the simplification of fluid dynamics equations. However, in reality, ideal fluids do not exist, and all real fluids exhibit some level of viscosity and other non-ideal behaviors.
Uniform flow occurs when the fluid velocity and properties are constant throughout the flow field, while non-uniform flow has varying velocity and properties across the flow field. In uniform flow, streamlines are parallel and the flow is steady, whereas in non-uniform flow, streamlines may converge or diverge and the flow can be unsteady.
Laminar flow. This type of fluid flow involves layers of fluid flowing parallel to each other in an orderly manner without mixing or turbulence.
In fluid dynamics, rotational flow involves the movement of fluid particles in a circular or spinning motion, creating vortices or swirls. On the other hand, irrotational flow occurs when the fluid particles move without any rotation, resulting in smooth and uniform flow patterns.
Irrotational flow in fluid dynamics is characterized by the absence of vorticity, meaning the fluid particles do not rotate as they move. This type of flow is often used to model the behavior of ideal fluids, such as air or water in certain conditions. Irrotational flow is commonly applied in aerodynamics, hydrodynamics, and the study of fluid motion around objects like aircraft wings or ships.

A two-dimensional doublet is a theoretical representation of fluid flow in which the fluid is assumed to circulate around a line vortex. It is a simplification used in fluid dynamics to model the behavior of flow around objects like airfoils or ships, where the flow can be represented by a combination of uniform flow and doublet flow to approximate the effects of lift and drag.

Ideal flow in transport phenomena refers to a theoretical state where the flow of fluids is smooth, predictable, and free of turbulence or disturbances. In this scenario, the fluid moves in a laminar manner, with layers sliding past each other without mixing. This concept is crucial for simplifying the analysis of fluid dynamics and heat transfer, allowing for easier mathematical modeling and predictions of behavior under various conditions. Ideal flow is often characterized by parameters such as constant viscosity and incompressibility.
Any fluid that has no resistance to shear stress and no compressibility is called "Ideal Fluid"
Steady flow is a condition in fluid dynamics where the flow parameters (velocity, pressure, temperature) at any point in the system do not change with time. This implies that the flow is constant and does not fluctuate. When analyzing fluid systems, steady flow simplifies calculations and allows for the use of conservation equations.
An irregular fluid flow refers to a fluid motion that is not consistent or smooth, characterized by fluctuations and turbulence in the flow pattern. It can be caused by factors such as obstacles in the fluid's path, changes in the flow velocity, or variations in fluid properties. Irregular fluid flow can affect the efficiency and performance of systems where fluids are involved, such as pipelines or aircraft wings.
