Pressure drop in flow across ceramic foams-a numerical and experimental study

The unique properties of ceramic foams make them well suited to a range of applications in science and engineering such as heat transfer, reaction catalysis, flow stabilization, and filtration. Consequently, a detailed understanding of the transport properties (i.e. permeability, pressure drop) of these foams is essential. This paper presents the results of both numerical and experimental investigations of the morphology and pressure drop in 10. ppi (pores per inch), 20. ppi and 30. ppi ceramic foam specimens with porosity in the range of 75-79%. The numerical simulations were carried out using a GPU implementation of the three-dimensional, multiple-relaxation-time lattice Boltzmann method (MRT-LBM) on geometries of up to 360 million nodes in size. The experiments were undertaken using a water channel. Foam morphology (porosity and specific surface area) was studied on post-processed, computed tomography (CT) images, and the sensitivity of these results to CT image thresholding was also investigated. Comparison of the numerical and experimental data for pressure drop exhibited very good agreement. Additionally, the results of this study were verified against other researchers[U+05F3] data and correlations, with varying outcomes

Impact of physical disability on pursuit of gardening activities in mid-aged women

Research on horticultural therapy approaches suggest that its positive impact on clients may extend beyond direct rehabilitation or vocational gains to more generally improved well-being. Persons in rehabilitation programs may relate to gardening as a previously enjoyed past time, or as a new activity for either leisure or employment purposes. While gardening is a popular leisure activity in many countries, few studies have looked at what specific gardening activities community-based populations pursue. As part of a larger mail-out survey looking at gardening interests of mid-aged women, a sub-sample of physically disabled women was compared to healthy age-matched women on gardening activities and interests. Physical and psychological functioning and well-being were also sampled. Both groups completed the SF-36 Health Survey for Australia/New Zealand, the Symptom Checklist-90-Revised, and a gardening questionnaire tapping gardening activities and hours per month on these activities, as well as the reasons for pursuing gardening. Group differences emerged on physical and psychological functioning variables, but for virtually all gardening variables, group differences were minimal. Overall findings suggest that for this sample of mid-aged women, the presence of physical disability or limitation did not adversely affect their access to and enjoyment of gardening activities
