Opis:
Scholarly publication is a leading requirement for the Doctor of Philosophy (PhD) program. Publishing articles, therefore, has become an appealing expectation for early-stage doctoral researchers (ESDRs). However, little has been done to address the dynamic relationship between the PhD and the academic publication system. The purpose of this study is to understand the intricately intertwined structures of PhD study and to explore the challenges related to scholarly publication. A group discussion method was deployed for data collection by recruiting international ESDRs (n=15) from three different countries. Primary results indicate that common anxiety is associated with the requirement to publish in high impact factor journals as well as the publication process. Quality supervision is recognized as inevitable to improve a mentor-mentee relationship and was found helpful in reducing the barriers to scientific publication. Moreover, the dominant structural factors of PhD study determine the ESDRs’ decision-making. The study suggests that the PhD study should remain research-intensive rather than simply for the sake of obtaining a higher qualification.

Opis:
An axial flow tubular heat exchanger has been experimentally investigated to augment the heat transfer rate with a novel swirl flow of air past the heated tubes. The novel design has been based on circular baffle plates provided with trapezoidal air deflectors of various inclination angles. The arrangement of tubes is kept the same throughout the experiment, in accordance with the longitudinal airflow direction. The tubes maintained a constant heat flux condition over the surface. Four deflectors with equal inclination angles were developed on each baffle plate, generating air swirl inside a circular duct carrying the heated tubes that increase air-side turbulence and, consequently, the surface heat transfer rate. The baffle plates were placed equidistant from each other at variable pitch ratios. The Reynolds number was kept in the range of 16000– 28000. The effect of pitch ratios and inclination angles on the thermo-fluid performance of the heat exchanger was studied. The investigations revealed an average improvement of 3.75 times in thermo-fluid performance for an exchanger with a deflector baffle plate with a baffle inclination angle of 50_ and a pitch ratio of 1.4 when compared to other inclination angles and pitch ratios.
