The adaptive dynamic mesh, user-defined functions, and six degrees of freedom (6DOF) solver provided in ANSYS FLUENT 14 are engaged to simulate the activating processes of the rotor of the Grumman WS33 wind system. The rotor is activated from stationary to steady operation driven by a steady or periodic wind flow and its kinematic properties and power generation during the activating processes. The angular velocity and angular acceleration are calculated directly by the post-processed real-time 6DOF solver without presuming a known rotating speed to the computational grid frame. The maximum angular velocity of the rotor is approximately proportional to the driving wind speed, and its maximal angular acceleration is also closely proportional to the square of the driving wind speed. The evolution curves of the normalized rotor angular velocities and accelerations are almost identical due to the self-similarity properties of the rotor angular velocities and accelerations. The angular velocity of the rotor will reach its steady value. One can use these steady angular velocities to predict the mechanical power generations of the rotor. The momentum analysis theory and the blade element momentum method are applied to predicted power generations and reveal good agreements with experimental data in the low wind speed range.
The purpose of this study was to investigate how bereaved clients recovered from grief and loss after receiving Kollar's solution-focused pastoral counseling (KSFPC) from a perspective of empowerment. Ten Taiwanese Christian clients (3 men, 7 women; M age = 42.5 yr., SD = 8.5), who had experienced a significant loss of a loved one within the past two years, were recruited from churches in northern Taiwan, forming a convenience sample. The clients, based on their time availability, were randomly assigned to one of the two pastoral counselors and had four KSFPC sessions. The grounded theory procedure was adopted for qualitative data analysis. Four prominent categories emerged from the open-ended questions, in-depth interviews, and interactive counseling notes, including First Encounter with Solution-focused Pastoral Counseling (SFPC), Transitional Life Re-Decision-Making Process, Reflections and Changes, and New Participatory Competencies, within which 12 axial categories and 42 meaning units were identified. The results support the use of KSFPC to empower clients' competence in recovery from grief and loss. Implications for future research and KSFPC practice are suggested.
Interviews were carried out with 10 Christian pastoral counselors to explore their perspectives on the use of Scripture and prayer in the counseling process. Grounded Theory was utilized. Five main categories including a theological framework of pastoral counseling, counselors' considerations of using Scripture and prayer, preparation for Christian spiritual intervention, implications of spiritual resources, and ethical issues in the pastoral counseling process were generated. The results suggest the theological framework of pastoral counseling is crucial to the use of Scripture and prayer, and the issue of a neutral response should first be clarified for clients. Basic guidelines for ethically using Scripture and prayer for working with Christian clients are proposed for further pastoral counselor training, practice, and research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
