Abstract

Background: Pneumatosis cystoides intestinalis is a rare intestinal disease characterized by single or multiple air cysts in the submucosa or subserosa of the intestinal wall. It is often accompanied by other gastrointestinal diseases. The clinical manifestations were nonspecific, and the diagnosis mainly depended on colonoscopy, imaging, and other auxiliary examinations. Case presentation: The reason for pneumatosis cystoides intestinalis's occurrence remains unclear. Enteral nutrition deficiency, especially the use of glucosidase inhibitors, may be involved in the pathogenesis of pneumatosis cystoides intestinalis in this patient. Here, we report a rare case of pneumatosis cystoides intestinalis in an elderly man who had been taking acarbose for diabetes for a long time. Colonoscopy of the patient was normal before taking acarbose. Conclusion: In patients with diabetes who are treated with glucosidase inhibitors for gastrointestinal symptoms, the possibility of pneumatosis cystoides intestinalis should be considered, and a thorough gastrointestinal examination should be performed in such patients.

Abstract

Center cone locating at the rear portion of turbine is the key component of the integrated afterburner. Numerical studies were carried out to investigate full-coverage film cooling on center cone at engine-realistic conditions, and the effects of thermodynamic and geometric parameters on cooling effectiveness and aerodynamic loss were discussed in detail. The numerical model was validated by the infrared measured experiments. Two recirculation vortices were generated on the cone surface, and cause the reverse ejection of coolant. These two recirculation vortices were promoted by increasing blowing ratio, and mixed with each other as the blowing ratio reaches 3.0. Along the streamwise direction, cooling effectiveness decreases and reaches the minimum value at the tip of cone, which is very different from the flat-plate film cooling. Cooling effectiveness increases with the increases of blowing ratio, hole diameter and density ratio, but decreases with the increases of hole pitch and spacing. The discharge coefficient increases with the increases of hole diameter and inclination angle, but decreases with the increases of blowing ratio, hole pitch and spacing. Pure film cooling and double-wall cooling were also compared. The introduction of jet impingement cooling can generate higher cooling effectiveness, especially at low and medium blowing ratio, but causes the notable increase of pressure drop.
