Numerical investigation of the effectiveness of effusion cooling for plane multi-layer systems with different

Dieter BOHN, Robert KREWINKEL

Frontiers in Energy 2009, Volume 3, Issue 4,   Pages 406-413 doi: 10.1007/s11708-009-0041-x

Abstract: Within Collaborative Research Center (SFB) 561 “Thermally Highly Loaded, Porous and Cooled Multi-Layer Systems for Combined Cycle Power Plants” at RWTH Aachen University, an effusion-cooled multi-layer plate configuration is investigated numerically by the application of a three-dimensional in-house fluid flow and heat transfer solver, CHTflow. CHTflow is a conjugate code, which yields information on the temperature distribution in the solid body. This enables a detailed discussion of the effects of a change in materials. The geometrical set-up and the fluid flow conditions derive from modern gas turbine combustion chambers and bladings. Within the SFB, two different multi-layer systems, one consisting of substrate made of CMSX-4 (a single-crystal super-alloy), an MCrAlY-bondoat and a ZrO thermal barrier coating (TBC), and the other consisting of a NiAl-alloy and a graded bondcoat/TBC, have been investigated. The grading will increase the life-span of the TBC as it can better compensate the different thermal expansion coefficients of different materials. The main focus in this study is on the different substrate materials, because the thermal conductivity of the NiAl is considerably higher than that of CMSX-4, which leads to different temperature profiles in the components. The numerical grid for the simulations contains the coolant supply (plenum), the solid body for the conjugate calculations, and the main flow area on the plate. The effusion-cooling is realized by finest drilled shaped holes with a diameter of 0.2mm. The investigation is concentrated on a cooling hole geometry with a laterally widened fan-shaped outlet, contoured throughout, and one without lateral widening that is only shaped in the TBC-region of the system. Two blowing ratios, =0.28 and =0.48, are investigated, both for a hot gas Mach number of 0.25. The results for the lower blowing ratio and the fully contoured hole are discussed as well as those of the higher blowing ratio and the non-laterally widened hole. These represent two characteristic cases.

Effectiveness of quality of care for patients with type 2 diabetes in China: findings from the Shanghai

Frontiers of Medicine 2022, Volume 16, Issue 1,   Pages 126-138 doi: 10.1007/s11684-021-0897-7

Abstract: This cross-sectional study aimed to investigate the quality of care of diabetes in Shanghai, China. A total of 173 235 patients with type 2 diabetes in 2017 were included in the analysis. Profiles of risk factors and intermediate outcomes were determined. The patients had a mean age of 66.43±8.12 (standard deviation (SD)) years and a mean diabetes duration of 7.95±5.53 (SD) years. The percentage of patients who achieved the target level for HbA1c (<7.0%) was 48.6%. Patients who achieved the target levels for blood pressure (BP)<130/80 mmHg and low-density lipoprotein-cholesterol (LDL-c)<2.6 mmol/L reached 17.5% and 34.0%, respectively. A total of 3.8% achieved all three target levels, and the value increased to 6.8% with an adaptation of the BP target level (<140/90 mmHg) for those over 65 years. Multivariable analysis identified the factors associated with a great likelihood of achieving all three target levels: male, young age, short diabetes duration, low body mass index, macrovascular complications, no microvascular complications, prescribed with lipid-lowering medication, and no prescription of antihypertensive medication. In conclusion, nearly 50% and one-third of the patients with diabetes met the target levels for HbA1c and LDL-c, respectively, with a low percentage achieving the BP target level. The percentage of patients who achieved all three target levels needs significant improvement.

Advanced manufacturing technology effectiveness: A review of literature and some issues

Sanjeev GOYAL, Sandeep GROVER

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 3,   Pages 256-267 doi: 10.1007/s11465-012-0330-7

Abstract:

Advanced manufacturing technology (AMT) provides advantages to manufacturing managers in terms of flexibility, quality, reduced delivery times, and global competitiveness. Although a large number of publications had presented the importance of this technology, only a few had delved into related literature review. Considering the importance of this technology and the recent contributions by various authors, the present paper conducts a more comprehensive review. Literature was reviewed in a way that will help researchers, academicians, and practitioners to take a closer look at the implementation, evaluation, and justification of the AMT. The authors reviewed various papers, proposed a different classification scheme, and identified certain gaps that will provide hints for further research in AMT management.

Topology optimization and seismic collapse assessment of shape memory alloy (SMA)-braced frames: Effectiveness

Aydin HASSANZADEH; Saber MORADI

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 3,   Pages 281-301 doi: 10.1007/s11709-022-0807-3

Abstract: This paper presents a seismic topology optimization study of steel braced frames with shape memory alloy (SMA) braces. Optimal SMA-braced frames (SMA-BFs) with either Fe-based SMA or NiTi braces are determined in a performance-based seismic design context. The topology optimization is performed on 5- and 10-story SMA-BFs considering the placement, length, and cross-sectional area of SMA bracing members. Geometric, strength, and performance-based design constraints are considered in the optimization. The seismic response and collapse safety of topologically optimal SMA-BFs are assessed according to the FEMA P695 methodology. A comparative study on the optimal SMA-BFs is also presented in terms of total relative cost, collapse capacity, and peak and residual story drift. The results demonstrate that Fe-based SMA-BFs exhibit higher collapse capacity and more uniform distribution of lateral displacement over the frame height while being more cost-effective than NiTi braced frames. In addition to a lower unit price compared to NiTi, Fe-based SMAs reduce SMA material usage. In frames with Fe-based SMA braces, the SMA usage is reduced by up to 80%. The results highlight the need for using SMAs with larger recoverable strains.
