A novel three-dimensional asymmetric oscillating heat pipe (3DAOHP) with unequal curvature radius of upper and lower bends has been designed. Setting the basic factor diameter from 1.9 mm to 6.2 mm, a verification experiment on criterion conventional maximum hydraulic (MHD) conducted. The results show that 3DAOHP can still perform normally transfer effectively, even if exceeds MHD by 98.1 %. And temperature profiles at each end does not obvious abnormalities. thermal performance also any...
The experimental study on exhaust denitration is carried out by using dielectric barrier discharge (DBD) reactor to generate non-thermal plasma (NTP).
In the midst of a rapidly evolving economic landscape, global demand for oil is steadily escalating. This increased has fueled marine extraction and maritime transportation oil, resulting in consequential uneven surge spills. Characterized by their abrupt onset, rapid pollution dissemination, prolonged harm, challenges short-term containment, spill accidents pose significant environmental threats. Consequently, it imperative to adopt effective reliable methods timely detection spills...
Due to the recent rapid growth of ocean oil development and transportation, offshore spill risk accident probability has increased unevenly. The marine poses a great threat coastal cities. Therefore, effective reliable technologies must be used monitor spills minimize disaster losses. Based on YOLO deep learning network, an automatic detection method was proposed. experimental data preprocessing operations include noise reduction, gray adjustment, local contrast enhancement. Then, real...
Vanadium-based catalysts are mainly used for marine diesel exhaust denitration. However, their poor catalytic ability at low temperature and sulfur tolerance, as well high toxicity cost, big turnoffs. AC (Activated carbon) exhibits good adsorption capacity in denitration because of its specific surface area chemical activity. In this paper, coal-based was simulating different conditions. The results show that the NO removal is an NO/N2 system. NO2 excellent NO2/N2 system, where desorbed. NOx...
So far, most of the experimental researchers studying removal diesel exhaust pollutants have done so with simulated gas, which cannot demonstrate ability catalysts accurately. Because activated carbon (AC) has low price, no secondary pollution, good adsorption performance, and certain catalytic activity, it application prospects in field marine pollutant removal. In this paper, particulate matter (PM), monoxide (CO), NOx from real gas by AC was studied. The results show that PM efficiency...
A diesel engine de-NO<sub>x</sub> system combining non-thermal plasma and activated carbon was set up. The efficiency reaches 91.8% 92.5% for simulated gas real exhaust gas, respectively. It has good potential to replace vanadium-based SCR.
Abstract In order to understand the heat transfer performance, startup, and fluid flow conditions of oscillating pipes (OHPs) with a hydraulic diameter far exceeding maximum (MHD) defined by dh,max≤2σBo/(ρl−ρv)g, an experimental investigation on OHP performance visualization was conducted. The effects input, working fluid, orientation motion investigated OHPs have been addition, detailed patterns tested were recorded high-speed camera from both vertical horizontal orientations. Results show...
Effective oil spill monitoring is critical for timely response to minimize the impact on environment. In difficulty in extracting suspected films from marine radar images, a semantic segmentation method was proposed. preprocessing of training samples similar scene, slicing solution used compensate small sample original data. The U-Net network classify film into two categories: real and suspected. Existing mainstream identification methods were compared. Experimental results demonstrate that...
Similar to the layout of an oscillating heat pipe (OHP), a quartz hybrid (HHP) with inner diameter 5 mm, exceeding 59.7 % capillary threshold OHP, was designed. The detailed thermal hydraulic behavior fluid in HHP has been revealed. It found that undergoes transfer mode transition from phase change pulsating flow. is also means liquid slugs can be dynamically and stably formed if input sufficient. single bubble growth multi-bubble coalescence are two ways form intermittent In addition, as...
Abstract For an oscillating heat pipe (OHP), the hydraulic diameter must be sufficiently small so that vapor plug and liquid slug can formed by capillary action. Therefore, should not exceed a critical value named maximum (MHD). In current research, glass OHP with of 6 mm was fabricated, ethanol used as working fluid (Figs. 1 2). With far exceeding (MHD) defined dh,max≤{2σBo[(ρl−ρv)g]}1/2, function. But flow pattern is very different from smaller than MHD, depends on filling ratio. When...
