Fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids—liquids and gases. It has several subdisciplines, including aerodynamics (the study of air and other gases in kineticism) and hydrodynamics (the study of liquids in kineticism). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, soothsaying weather patterns, understanding nebulae in interstellar space and modelling fission weapon detonation.Fluid dynamics offers a systematic structure—which underlies these practical disciplines—that embraces empirical and semi-empirical laws derived from flow quantification and used to solve practical quandaries. The solution to a fluid dynamics quandary typically involves the calculation of sundry properties of the fluid, such as flow velocity, pressure, density, and temperature, as functions of space and time.

A fore the twentieth century, hydrodynamics was synonymous with fluid dynamics. This is still reflected in names of some fluid dynamics topics, like magnetohydrodynamics and hydrodynamic stability, both of which can withal be applied to gases, To increment the overtness and facilitate of avail of open access scientific and scholarly journals top online publishing journals are indexed in different indexing and archiving accommodations. Indexing provides facile access of the article online. The top online publishing journals publish articles which are cited as references by many authors in their work. Citations are paramount for a journal to get impact factor. Impact factor is a quantification reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more consequential than those with lower ones. Indexing provides facile access of the article online. The international journals are among the best open access journals in the world, set out to publish the most comprehensive, pertinent and reliable information predicated on the current research and development on a variety of subjects. This information can be published in our peer reviewed journal with impact factors and are calculated utilizing citations not only from research articles but additionally review articles (which incline to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and endeavor to increment their number expeditiously. Impact factor plays a major role for the particular journal.
