Endwall film cooling protects vane endwall by coolant coverage, especially at the leading edge (LE) region and vane-pressure side (PS) junction region. Strong flow impingement and complex vortexaa structures on the vane endwall cause difficulties for coolant flows to cover properly. This work aims at a full-scale arrangement of film cooling holes on the endwall which improves coolant efficiency in the LE region and vane-PS junction region.

The endwall film holes are grouped in four-holes constructal patterns. Three ways of arranging the groups are studied: based on the pressure field, the streamlines or the heat transfer field. The computational analysis is done with the k-ω SST model after validating the turbulence model properly.

By clustering the film cooling holes in four-holes patterns, the ejection of the coolant flow is stronger. The four-holes constructal patterns also improve the local coolant coverage in the “tough” regions, such as the junction region of the PS and the endwall. The arrangement based on streamlines distribution can effectively improve the coolant coverage and the arrangement based on the heat transfer distribution (HTD) has benefits by reducing high-temperature regions on the endwall.

A full-scale endwall film cooling design is presented considering interactions of different film cooling holes. A comprehensive model validation and mesh independence study are provided. The cooling holes pattern on the endwall is designed as four-holes constructal patterns combined with several arrangement choices, i.e. by pressure, by heat transfer and by streamline distributions.

Employability skills have transformed from the acquisition of university degrees to possessions of cognate skills other than only degrees that can help employees secure employment in contemporary work environments. This study evaluates essential skills that will prepare millennia of youths and graduates for employment in the present job market. The study investigated four major hypotheses to underscore the employability opportunities of graduates in challenging 21st-century work environments.

To clearly gain an understanding of women’s disparity in society, the study employed a qualitative approach to evaluate the incidence of gender prejudice in a men’s dominant world. The study utilised two distinguished sampling strategies, purposive and snowballing sampling techniques, which were deemed suitable and useful due to the nature of the study. The study recruited 42 participants by conducting semi-structured interview sessions for the study. The study employed a deductive approach to analyse the data obtained from participants. A thematic content analysis was used to take away prejudice and establish an overarching impression of the interviewed data. Atlas.ti was used to analyse the transcribed interview data from the participants to establish common themes from the surveyed informants.

The results of this investigation indicated that there is a deep-rooted trend of institutionalised men’s dominance in politics and religious leadership. Women perceived less representation and men dominated the two domains of existence in their local environment. The study established that women are optimistic about a turnaround narrative on gender equality in politics and religious leadership. They expressed their concern about strengthened public debate and campaigns on women’s representation, and against gender discrimination. The study further shows that women are influencing the ethical and moral sense for change against women’s neglect in society. They expressed their concerns against the selection of people into political offices for elected political posts and observed the peculiarity of political godfathers fixing their favourite men into those offices.

The study discovered that women are leading campaigns for their representation in politics as well as church leadership today. The novelty of this study bothering around two domains of women’s lives – politics and religion, in particular, church leadership. These have not been evidence before in a study.
