All fluid flow is classified into one of two broad categories. The fluid flow can be either laminar or turbulent, and therefore these two categories are:<\/p>\n<ul>\n<li><strong>Laminar Flow<\/strong><\/li>\n<li><strong>Turbulent Flow<\/strong><\/li>\n<\/ul>\n<p><strong>Laminar flow<\/strong> is characterized by <strong>smooth<\/strong> or <strong>regular paths<\/strong> of particles of the fluid. Therefore the laminar flow is also referred to as <strong>streamline or viscous flow<\/strong>. In contrast to laminar flow, <strong>turbulent flow<\/strong> is characterized by the <strong>irregular movement<\/strong> of particles of the fluid. The turbulent fluid does not flow in parallel layers, the lateral mixing is very high, and there is a disruption between the layers. <strong>Most industrial flows<\/strong>, especially those in nuclear engineering, <strong>are turbulent<\/strong>.<\/p>\n<p>The flow regime can also be classified according to the <strong>geometry of a conduit<\/strong> or flow area.

On the other hand, <strong>external flow<\/strong> is such a flow in which boundary layers develop freely, without constraints imposed by adjacent surfaces.

The fluid flow equations and relationships normally discussed in this section are for the flow of a single phase of fluid, whether liquid or vapor.<\/p>\n<p>When the simultaneous flow of liquid and gas occurs at certain important locations in fluid flow systems, the problem must be solved <strong>as a two-phase flow<\/strong>. The relatively simple relationships used for analyzing single-phase flow are <strong>insufficient<\/strong> for analyzing two-phase flow.<\/p>\n<h2>Two-phase Fluid Flow<\/h2>\n<p>By definition, <strong>multi-phase flow<\/strong> is the interactive flow of <strong>two or more<\/strong> distinct phases with common interfaces in, say, a conduit. Each phase, representing a volume fraction (or mass fraction) of solid, liquid, or ga搜索引擎优化us matter, has its <strong>own<\/strong> properties, <strong>velocity<\/strong>, and <strong>temperature<\/strong>.<\/p>\n<p>A multi-phase flow can be a simultaneous flow of:<\/p>\n<ul>\n<li>Materials with <strong>different states or phases<\/strong> (e.g.,, water-steam mixture).<\/li>\n<li>Materials with <strong>different chemical properties<\/strong> but in the same state or phase (e.g.,, oil droplets in water).<\/li>\n<\/ul>\n<p>There are\u00a0many combinations in industrial processes, but the <strong>most common<\/strong> being the simultaneous flow of <strong>steam and liquid water<\/strong> (as encountered in <a title=\"Steam Generator\" href=\"http:\/\/sitepourvtc.com\/steam-generator\/\"><strong>steam generators<\/strong> <\/a>and <strong>condensers<\/strong>). In reactor engineering, a great deal of study has been performed on the nature of <strong>two-phase flow<\/strong> in case of a loss-of-coolant accident (<strong>LOCA<\/strong>), an accident of importance in reactor safety, and all thermal-hydraulic analyses (<strong>DNBR analyses<\/strong>).<\/p>\n<h2>Characteristics of Multiphase Fluid Flow<\/h2>\n<p>All multi-phase flow problems have features that are characteristically different from those found in single-phase problems.<\/p>\n<ul>\n<li>In the case of steam and liquid water, the <strong>density<\/strong> of the two phases <strong>differs by a factor of about 1000<\/strong>. Therefore the influence of gravitational body force on multi-phase flows is of much greater importance than in the case of single-phase flows.<\/li>\n<li>The <strong>sound speed<\/strong> changes dramatically for materials undergoing a phase change and can be orders of magnitude different. This significantly influences a <strong>flow through an orifice<\/strong>.<\/li>\n<li>The relative <strong>concentration<\/strong> of different phases is usually a dependent parameter of great importance in multi-phase flows, while it is a parameter of no consequence in single-phase flows.<\/li>\n<li>The phase change means flow-induced pressure drops can cause further phase change (e.g.,, water can evaporate through an orifice), increasing the relative volume of the ga搜索引擎优化us, compressible medium and increasing efflux velocities, unlike single-phase incompressible flow where decreasing of an orifice would decrease efflux velocities.<\/li>\n<li>The spatial distribution of the various phases in the flow channel strongly affects the flow behavior.<\/li>\n<li>There are many types of instabilities in multi-phase flow.<\/li>\n<\/ul>\n<\/div><\/div><div   id="8n9s8rpp6h"    class=\"su-spoiler su-spoiler-style-default su-spoiler-icon-plus su-spoiler-closed\" data-scroll-offset=\"0\"><div   id="8n9s8rpp6h"    class=\"su-spoiler-title\" tabindex=\"0\" role=\"button\"><span class=\"su-spoiler-icon\"><\/span>Laminar vs. Turbulent Flow<\/div><div   id="8n9s8rpp6h"    class=\"su-spoiler-content su-u-clearfix su-u-trim\">\n<h2>Laminar Flow<\/h2>\n<p><a href=\"http:\/\/sitepourvtc.com\/wp-content\/uploads\/2016\/05\/Flow-Regime.png\"><img loading=\"lazy\" class=\"alignright size-medium wp-image-14393\" src=\"http:\/\/sitepourvtc.com\/wp-content\/uploads\/2016\/05\/Flow-Regime-300x175.png\" alt=\"flow regime\" width=\"300\" height=\"175\" srcset=\"https:\/\/sitepourvtc.com\/wp-content\/uploads\/2016\/05\/Flow-Regime-300x175.png 300w, https:\/\/sitepourvtc.com\/wp-content\/uploads\/2016\/05\/Flow-Regime.png 1012w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a>In fluid dynamics,<strong> laminar flow<\/strong> is characterized by <strong>smooth or regular paths<\/strong> of fluid particles, in contrast to <strong>turbulent flow<\/strong>, which is characterized by the <strong>irregular movement<\/strong> of particles of the fluid.
