The structure of the flow of a reentry capsule MUSES-C and the resulting base pressure has been numerically investigated. A computational fluid dynamics CFD analysis of the flow in base region of a planetary reentry capsule is studied. The present paper uses CFD to investigate the steady state perfect fluid dynamics of a reentry space capsule at zero angle of incidence with emphasis on the flow physics of the capsule. A CFD based investigation of the complex flowfield over the MUSES-C is carried out employing finite volume code. The present paper investigates phenomena associated with the flow in the fore body and as well as base region of the MUSES-C. The present paper is aimed to analyze numerical solutions of viscous flow past the reentry capsule and focusing on the characteristics of the near wake flow detachment, free shear layer evolution, lip shock formation, recirculation region, and upstream influence. The approaching boundary layer separates at the corner and the free-shear layer is formed in the wake region. A low pressure is formed in the base region of the capsule which is characterized by a low-speed recirculation zone.

Purpose: This study design explores the literature produced and published in journals indexed in the Scopus-Elsevier database in terms of machine accidents. Methods: We acquired support from the Scopus-Elsevier information base and its listed journals to download the information for this examination. The data covers 48 years of exploration. This examination is separated into five spells to analyze; year-wise, sort of reports, an arrangement of subjects, creators design transport, an association of the primary creator with the nation, and dialects of a composition, distributed from 2019 – 1972. Results: One hundred forty-six different types of documents were written by 395; 2.7% authors in eleven languages and categories in eleven subject areas published in the Scopus-Elsevier database from 2019- 1972. Majority of 81; 55% documents scripted as articles, followed by conference papers. The first spell published 84; 57%, remaining 62; 42.4% documents published in four spells. With 47 documents, Industrial Engineering got maximum attention, Road, and Traffic with 46 documents, and Agricultural and Biological Sciences with 17documents and stand on second and third. The majority 102; 69.8% of documents written in collaboration, and 44; 30.1% documents scripted by single or solo authors. Out of 146 papers, the literature (85; 58.2%) of papers published by five countries, and the remaining 61; 41.7% documents contributed by 26 countries out of 31 countries. Conclusion: Education has power to move society towards science and technology. This study revealed that, the ultimate goal of library professionals is to save the time of reading through the ease of system with educational programs, instead of this the subject got lase attention among the eyes of library professionals.

Africans and the rest of the world have started embracing the use of herbal products. The need to develop machines for indigenous fabrication that meet the standard for acceptability in terms of hygiene and engineering standard necessitated this concept of using steam to extract the pigment from back of trees and leaves especially roselle (Hibiscus sabdariffa L) (red variety) popularly called zobo in Nigeria culled from zoborodo (Hausa language).The red pigment can be extracted through this machine. Reduction in material handling and commercial production is favored with this machine. It comprises the heating section, water section and the herbal material section which lead to the condenser and the mixer where other ingredients are introduced. It requires 2030038 .8 kj as an ideal heat to evaporate the water for extraction using electricity in one hour .Materials used are corrosion resistant materials like stainless steel and plastic.
