One of the possible origins of High Cycle Fatigue in a compressor blade is the rotating stall under the influence of (rotating) inlet pressure or temperature distortion leading to a varying angle of attack on the compressor blades. This paper will be oriented towards the propagation of total pressure and total temperature nonuniformities in axial flow fans and compressors and their subsequent e...

This study aims to present appropriate selection methods for evaluation, analysis, and comparison between different ballast water treatment technology systems in order make good decisions selecting the most optimal system. research designed a filter device on John Lie training ship prevent marine pollution due species movement through transfer process by referring D2 standard of IMO Ballast Wat...

Background: Inlet patch (IP) lesion is the presence of gastric columnar epithelial tissue outside of the stomach. Symptoms such as a lump in the throat, chronic cough, laryngitis, or other mouth-throat symptoms may be IP-related only and have no other abnormalities. This study aimed to determine the relationship between globus sensation and structural disorder of Inlet Patch in patients with ga...

The connected water pipe facility is an important fire extinguishing for supplying to firefighters on the floor. However, there are cases where not supplied quickly, which also caused by inability find connection inlet owing unclear regulations installation location of safety standards. If found, fire-fighting tactics involving ropes used, takes a lot time. To improve this problem, we confirmed...

Acquired port-wine stain is a rare vascular lesion that mimics a congenital port-wine stain clinically and histologically, but is acquired after birth. A survey on more than 60 reported cases in the literature reveals that most of these cases are idiopathic, but some of the cases developed after physical or mechanical trauma, hormonal changes, chronic sun exposure, and medications (OCP, i...

A supersonic separator has been introduced to remove water vapour from natural gas. The mechanisms of the upstream and downstream influences are not well understood for various flow conditions from the wellhead and the back pipelines. We used a computational model to investigate the effect of the inlet and outlet flow conditions on the supersonic separation process. We found that the shock wave...

In order to prevent the backward flow of piezoelectric pumps, this paper presents a single-active-chamber piezoelectric membrane pump with multiple passive check valves. Under the condition of a fixed total number of passive check valves, by means of changing the inlet valves and outlet valves' configuration, the pumping characteristics in terms of flow rate and backpressure are experimentally ...

The paper presents the effects of blend injection and dual strategies on mixture formation combustion syngas-biogas-hydrogen fueling engine working in solar-biomass hybrid renewable energy system. research was performed by simulation method a retrofitted Honda GX200 spark-ignition engine. results show that at end compression process, case 50% syngas-50% biogas, fuel-rich zone positioned top cha...

The dynamic melting of CuO–coconut oil was addressed in a latent-heat thermal energy storage unit loaded with copper foam. In new design, the is made shell-tube-shaped chamber, which liquid flow hot phase-change material (PCM) allowed to enter chamber from port at bottom and exit top. A fin mounted forward entrance PCM toward solid regions. control equations were solved using finite element met...
