The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RÉSUMÉ

The present paper makes an effort to visualize the flow patterns and other characteristics of both forced and free vortex motion by an experimental method. Works of both experimental and numerical have been conducted to understand the various features of vortex motion and its effects on drag, etc. Here colored die has been used to understand the profiles and an arrow shaped strip marks the difference between irrotational and rotational flow. In the forced vortex motion it has been observed that the parabolic profile remains invariant with the rpm of the paddle and the height of the lowest point of the profile decreases with the increase in paddle speed. In the free vortex motion, it is observed that the hyperbolic profile does not change with the change in flow rate. In this case, suction is created towards the centre where as in the case of forced vortex no such suction arises. With the reduction in the size of the orifice diameter, the profile becomes less steep for free vortex. In this case the velocity profile in the core region is straight; as the radius increases the profile becomes rectangular hyperbola where as in the case of forced vortex the velocity profile maintains its linear nature for the entire range of radii.
