    The Concept of flipped class room technique has been recently introduced in Higher Education. Recent studies indicate that student attendance at lectures drastically reduced both at nationally and internationally, has prompted researchers to introduce new methods in course delivery and classroom engagement. It makes students to gain necessary knowledge before class and allows instructors to guide the students to participate in discussion during the lecture hours. Also, the students share their knowledge during the class. It is observed that most of the Engineering programs have lagged in integrating the blended learning approach into curricula. The present case study is an attempt to prepare students before entering the class and provide deeper thinking in the subject of study. The instructor provided material for the selected subject (fluid mechanics) for eight selected topics before starting of the class and had interaction with the students during the delivery. From the case study carried out, it is found that students actively participated in the flipped teaching approach and also observed that the efficiency of the students improved during the course of delivery.

  • Effect of convex curvature on the mean flow characteristics of a three-dimensional wall jet

    Several studies of jets impinging on a plane surface have already been made. This paper presents the results of effect of convex curvature on the mean flow characteristics of wall jets. Measurements were performed up to an axial distance of 60 times the slot widths of the orifice selected in the present work. The flow properties considered in the present paper are the mean velocity profiles, maximum velocity decay and the growth of half width. Comparisons have been made with the two-dimensional wall jet. It is observed that the longitudinal mean velocity profiles exhibit similarity for the convex wall jet when compare to plane wall jet. All the mean velocity profiles are self-similar at all the longitudinal distances measured in the present study. It is shown that the decay of the maximum velocity is higher for a three-dimensional wall jet on convex surface compare to plane wall jet. It is also found that the growth of half width is higher on curved surface when compared to plane wall jet.
