The purpose of this study was to investigate the factors that might influence the social entrepreneurial Intention of state undergraduate students in Sri Lanka. The Theory of planned behaviour was tested in the context of state undergraduate students in Sri Lanka. Exogenous variables included Personal Attitude, Subjective Norm, Perceived Behavioural control, and Prior experience of social problems on social entrepreneurial Intention were studied. Using validated items from prior literature, the research instrument was developed. Undergraduate students from nine state universities in Sri Lanka provided the data for this quantitative study. Using IBM's SPSS 25 and AMOS 22 software, structural equation modelling was applied to extract insights from the valid data. Outcomes of the confirmatory factor analysis, followed by a structural model evaluation revealed a positive relationship exists between Social Entrepreneurial Intention and Employment attitude and social entrepreneurial Intention and Perceived behavioral control. However, the results did not support the relationships between social entrepreneurial Intention and subjective Norms and prior experiences with social problems and social entrepreneurial attitude. State university graduate unemployment has been a major socio-politico-economic problem in Sri Lanka, and Social entrepreneurship can be proposed as a viable career option. However, limited research has been carried out in the Sri Lankan context. This research will shed light on the antecedent factors that affect social entrepreneurial Intention and assist policymakers in developing appropriate strategies for promoting Social entrepreneurship among undergraduates.

This paper aims to assist the thermal stratification in hot water storage during the partial discharge water. Three different types of curved baffle have been studied each one placed in the bottom of a rectangular standard conventional tank in order to reduce the turbulence mixing of inlet jet. The purpose of this investigation is to numerically study the impact of the curved baffle within a vertical hot storage tank and compare three different baffle designs to select the best one. A three-dimensional computational fluid dynamic (CFD) model was performed using the commercial software package CFX 18. The numerically simulated tank result was validated against the experiment data. The numerical transient temperature distribution and the flow characteristics were analyzed, and then a comparison was made between the three baffle designs and the calculated performance parameter. The results manifested that the curved baffle has a significant effect for enhancing the thermal stratification at high flow rates. Design C showed the best thermal stratification due to the downward curvature shapes.
