Abstract
Purpose
This study aims to study hollow droplet collisions for their hydrodynamic behavior and jet properties.
Design/methodology/approach
The volume of fluid (VOF) method was used to simulate a hollow impact using OpenFoam software (VOF).
Findings
The height of the edge-jet decreased as the air diameter (d) and length of the concave surface (L) increased. Height is specific for case 1 at t = 4 ms and its value is 3 mm. The minimum height is 0.585 mm in case 5. Also, the length of the edge-jet changed with time and decreased with the increasing length of concave and air diameter. The maximum length observed in case 1 was 9.23 mm, and the minimum appeared in case 5, in which the length was 0.68 mm.
Originality/value
The impact of a hollow droplet on a solid concave surface was numerically analyzed in this paper at various lengths of surface and shell thicknesses.

Abstract
Purpose
Responsiveness is one of the key components of good governance and one of the ultimate goals of health systems. The purpose of this study was to investigate the importance and level of health system responsiveness (HSR) from the perspective of people with disabilities in Iran.
Design/methodology/approach
This cross-sectional study was carried out using multi-stage sampling in Kurdistan province in 2020. Of 1,067 participants, 889 and 520 had used outpatient and inpatient services, respectively. HSR questionnaire developed by World Health Organization was completed.
Findings
The dimensions of prompt attention (97%) and social support (81%) were the most and the least important dimensions for the respondents, respectively. In general, 43.6% of the respondents reported a “poor” status for HSR.
Research limitations/implications
Designing targeted interventions to increase the level of health system responsiveness, especially with a focus on dimensions that are important to respondents but have weak performance, such as communication, confidentiality and autonomy, is suggested based on the findings of this study.
Originality/value
This is the first study performed on HSR from the perspective of people with disabilities in Iran. The findings of this study could be of interest to health policy makers to understand and improve healthcare experiences for marginalized populations globally.
