A few earlier studies presented infeasible heatline trajectories for natural convection within annular domains involving an inner circular cylinder and outer square/circular enclosure. The purpose of this paper is to revisit and illustrate the correct heatline trajectories for various test cases.

Galerkin finite element based methodology and space adaptive grid have been used to simulate natural convective flows within the annular domains. The prediction of heatlines involves derivatives at the nodes, which are evaluated based on finite element basis functions and contributions from neighboring elements.

The heatlines in the earlier work indicate infeasible heat flow paths such as heat flow from one portion to the other of isothermal hot walls and heat flow across the adiabatic walls. Current results illustrate physically consistent heat flow paths involving perpendicularly emerging heatlines from hot to cold walls for conductive transport, long heat flow paths around the closed-loop heatline cells for convective transport and parallel layout of heatlines to the adiabatic walls. Results also demonstrate complex heatlines involving multiple flow vortices and complex flow structures.

Current work translates heatfunctions from energy flux vectors, which are determined by using basis sets. This work demonstrates the expected heatline trajectories for various scenarios involving conductive and convective heat transport within enclosures with an inner hot object as a first attempt, and the results are precursors for the understanding of energy flow estimates.

The purpose of this paper is to explain how and why the intangible critical success factors (CSFs) determine the outcomes of public-private partnerships (PPP) projects in e-governance.

Drawing from the literature, PPP was conceptualized as an organization which facilitates the creation of social capital. It is argued that the intangible CSFs correspond to the key dimensions of the social capital that drives the development of intellectual capital in the course of addressing the challenges faced during the execution of an e-governance project. These efforts determine the accomplishment of the desired project objectives. The emergent framework was applied to an e-governance PPP project to anecdotally exemplify how the deficiency of organizational characteristics impedes the formation of social capital, resulting in project failure.

A theoretical framework was developed to illuminate the mechanisms and the attendant propositions that explain how and why the intangible factors influence the PPP outcomes.

This study fills a critical gap in the literature on PPP projects in general, and on e-governance projects in particular. It also extends the application of the social capital framework from an intra-organizational to an inter-organizational context.

The results of this study foster a better understanding of the drivers of success in managing a PPP model in e-governance initiatives.

This research work would help in improving the formulation and management of PPPs in the emerging economies, which could potentially enhance the societal outcomes.

The explanatory framework of this research serves as a useful perspective to address policy and program implementation issues of PPP initiatives in e-governance.
