Packed-bed thermocline tank with sensible fillers is a cost-effective option for thermal energy storage (TES). In real charging and discharging, the stability disturbed expansion occurs due to various factors, leading decreased global performances of tank. The purpose this work experimentally numerically study impact inlet configuration insulation on in lab-scale under operating parameters. Fir...

Quentin Skinner is an intellectual historian known for his pioneering work on early-modern European political thought. He was educated at Bedford School and Gonville and Caius College, Cambridge. Author of such works as The Foundations of Modern Political Thought (1978) and Visions of Politics (2002) he served as the Regius Professor of History at the University of Cambridge, and currently as t...

A filling operation generates continuous changes over the shape of an air–water interface, which can be captured using a 3D CFD model. This research analyses influence different hydro-pneumatic tank pressures and air pocket sizes as initial conditions for studying rapid operations in 7.6 m long PVC pipeline with irregular profile, OpenFOAM software. The analysed scenarios were validated experim...

Four clones of murine leukemia viruses (PVC-111, PVC-211, PVC-321, and PVC-441) were isolated from a paralyzed Fischer rat which had been infected with rat-passaged Friend leukemia virus. PVC-211 and PVC-321 viruses induced hind leg paralysis in rats and killed them within 1 month, and PVC-441 did so within 2 months after infection, whereas PVC-111 did not within 4 months. PVC-321 and PVC-441 b...

Packed-bed single-tank thermocline system with reduced cost is an alternative to the conventional two-tank for thermal energy storage. This work systematically explores wall impact on behavior of packed-bed tanks. For this purpose, adapted transient models were developed and fully exploited first time. Two tank configurations investigated compared: a high-temperature pilot-scale steel low-tempe...

One of the ways to achieving net-zero concept in construction industry is use alternatives Portland cement (OPC) and virgin aggregates for concrete manufacturing. Recycled rubber polyvinyl chloride (PVC) conjunction with low-carbon binders can be potentially utilised substitute natural sand reduce negative environmental impacts OPC. A replacement (up 70% by volume) alkali-activated materials (A...
