The aim of the study was to investigate the functional performance in children with spina bifida, using the Pediatric Evaluation of Disability Inventory （PEDI） to look into capacity of twen- ty-eight children with spina bifida with lesions at different levels in different dimensions of self- care, mobility and social function. Mean age of the patients was 3.5 ± 2.3 （1-10） years. In the muscle test carried out, 13 patients （44.8%） had no movements including pelvic elevation in lower extremity muscles and they were at level 5. Sixteen patients （54%） were non-ambulatory according to the Hoofer ambulation classification. Raw and scale scores in the self-care, mobil- ity and social function domains both in the functional skill scale and in the caregiver scale were found to be lower compared to the data of the normal population. A statistically significant correlation was observed in the self-care values of the Functional Skills Scales and the Caregiver Assistance Scale measurements, which was positive for age and negative for Functional Ambu- lation Scale and muscle test （P 〈 0.05）. A positive relation was found between the Functional Skills Scales-mobility area and age while a negative relation was observed between Functional Ambulation Scale and muscle test （P 〈 0.005）. A negative relation was also found between Care- giver Assistance Scale-mobility and Functional Ambulation Scale and muscle test （P 〈 0.005）. In our study, the functional performance of the children was found to be low. Low-level lesions, encouraging muscular strength and independence in mobility are all very important factors for functional independence.

Simulation of Natural Convection in a Cavity:Cooling with Top versus Bottom Partition`

引用

Journal of Energy and Power Engineering 2019年第9期13卷 327-332页

Natural convection in a square cavity is studied numerically with vertical hot walls and a cold partition located at the bottom or top walls. The effect of orientation of partition on isotherms, flow patterns, and heat transfer is analyzed for different fluids and Rayleigh numbers. The placement of partition is found to considerably influence the isotherms, flow patterns, and heat transfer. Heat transfer rate is observed always to increase when the partition is moved from bottom to top wall.

Effect of Fin Orientation and Length on the Rayleigh-Benard Convection

引用

Journal of Energy and Power Engineering 2017年第5期11卷 317-335页

作者： E. Evren selamet A. selamet and R. Dehner Department of Mechanical and Aerospace Engineering Ohio State University Columbus OH 43210 USA

Natural convection driven by the temperature difference of horizontal top and bottom surfaces of an enclosure containing air, Pr = 0.7, and fins of different arrangements at different lengths is studied numerically for Ra = 105 and 5 × 10^5. Evolution of heat transfer rates （Nusselt number） is illustrated along with various, steady or unsteady, cellular flow structures and temperature patterns. The effect of fin length and placement on flow regime and heat transfer is established. Different fin orientations at the walls are observed to introduce considerable unsteadiness in some cases, requiring close investigation in order to design systems for specific purposes.

Simulation of the Rayleigh–Benard Convection in a T-Shaped Cavity

引用

Journal of Energy and Power Engineering 2018年第11期12卷 545-552页

作者： E. Evren selamet A. selamet R. Dehner Ohio State University Mechanical and Aerospace Engineering Columbus OH 43210 USA

Rayleigh-Benard convection driven by the temperature difference between top and bottom surfaces of a T-shaped cavity with two different boundary conditions is studied numerically. Steady or unsteady cellular flow structures and temperature patterns are illustrated along with the evolution of heat transfer rates (Nusselt number, Nu). The cavity is filled with fluids of various Pr (Prandtl number), including 0.024, 0.71, 6, and 450. The effect of Pr and Ra (Rayleigh number) on the flow regime and heat transfer is established, while comparing the results also with those of the square cavity.
