Detached eddy simulation of unsteady flow over a frontal cavity
(American Institute of Aeronautics and Astronautics, 2023)
Frontal cavity consists of complex unsteadiness which causes bow shock instabilities when the body is moving at supersonic or hypersonic speed through a fluid. These complex unsteady flow fields are an important practical ...
Designing products for older people’s social and emotional needs: a case study
(Anthropology and Aging, 2023-11)
The products that we use in our living environment greatly assist us in maintaining health and independence as we age. Much research has been conducted on the physical ergonomic needs in product design for older people, ...
Health service design for older people the role of community, and the community and voluntary sector in the implementation of the living well at home piece of the integrated care programme for older people in kilkenny
(South East Technological University, Carlow., 2023-01-12)
The Integrated Care Programme for Older People (ICPOP) is part of how health and social care delivery is being envisaged in Ireland (ICPOP, 2018). The Living Well at Home piece of ICPOP, includes community and the community ...
Co-designing with engineers for community engagement in rural Uganda
(Cambridge University Press, 2023-05-04)
Co-design is seen as crucial for designing solutions for resource-constrained people living in
developing countries. To best understand their needs, user engagement and co-design
strategies need to first be developed. ...
An assessment of radiation models utilized in CFD for thermal and fluid analysis in interior building spaces with large glazing
(AIP Publishing, 2023)
This paper investigates the effects of using the S2S and the DO method in the CFD simulation of a cavity to identify
a convenient model for simulating radiative heat transfer. A 3D model for an office room fitted with a ...
A concept of aerospike nozzle for cold spray additive manufacturing: towards a potential solution for preventing the issue of clogging
(ASM International, 2023-05-22)
The clogging, a frequent gas passage deformation phenomenon because of powder accumulation on inner nozzle wall, is a major issue in long duration Cold Spray (CS) operations and a major challenge for Cold spray technology ...
Investigation of a modified circular nozzle for cold spray applications
(ASM International, 2023-05-22)
The current work numerically evaluates the efficacy of a coflowing nozzle for cold spray applications with the aim to mitigate nozzle clogging by reducing the length of its divergent section. The high-pressure nitrogen ...
Mach number dependence of flow instability around a spiked body
(AIP Publishing, 2023-05-05)
A forward-facing aerospike have been identified as a passive flow control device for enhancing the aerodynamic efficiency and reducing the heat transfer in high-speed flows. In addition, it has been reported that the ...
Numerical study of oblique detonation wave control for fuel blends
(2023)
The current study is motivated to develop control strategies for oblique detonation wave formation on a finite length wedge in a premixed methane-air mixture. The effectiveness of hydrogen blends (0 - 100%) to methaneair ...
Unsteady DSMC Simulation of blunt nose with spike at hypersonic rarefield flows
(2023-03-29)
To design an efficient ram-air intake for an air-breathing propulsion system for VLEO (Very-Low) / SLEO (Super Low) Earth Orbit satellites requires consideration of the unsteady effects in the hypersonic low-density or ...
