ABSTRACT A mathematical model is presented of the process of particle sedimentation from a fluid-solid slurry while flowing through a vertical slot. The differential equations describing the process consist of 1st order, non-linear, partial differential equation and a 1st order, ordinary differential equation. These two equations have been solved using a forward difference technique. Results for typical sets of system parameters are presented and discussed. The model finds practical application to solid-waste disposal processes and to petroleum reservoir stimulation processes. 相似文献

ABSTRACTCities, with their increasing populations, are host to a range of issues including non-climatic factors due to the prevailing development paradigm, discriminatory urbanisation patterns, and weak governance structures. Climate change poses an additional challenge and exacerbates existing vulnerabilities affecting cities and its people, especially the urban poor. This paper highlights the barriers and enablers to climate change-related adaptation experienced in some of Bengaluru’s informal settlements. The barriers described in the paper include economic, social, governance and information related issues that impede local actions and increase vulnerabilities. Enabling factors such as improving social and human capital, gaining formal recognition and most importantly support from agencies (e.g. local government, civil societies, and community leaders), help overcome some of the barriers or challenges. Hence, local level adaptation measures mainstreamed with local developmental agendas help address some of the structural causes of vulnerability. Contextual policies and interventions can facilitate successful local level adaptation measures. 相似文献
