Abstract This work presents the experimental results of a fluid dynamic investigation to characterize injection supercritical water in combustion chamber an internal engine. Particle Image Velocimetry (PIV) analysis is carried out optically accessible 2-stroke Diesel A prechamber, equipped with two optical accesses connected main cylinder through tangential duct so that piston stroke induces sw...

Here, a large-eddy simulation and finite-rate chemistry solver (see Kahila et al. Combustion Flame, 2019) is utilized to investigate diesel spray assisted ignition of lean methane-air mixture. A compression heating model emulate the ambient temperature pressure increase in (CI) system. The key parameter start injection (SOI) relative virtual top dead center (TDC), where peak adiabatic pressure/...

Mice have been employed as models of cancer for over a century, providing significant advances in our understanding of this multifaceted family of diseases. In particular, orthotopic tumor xenograft mouse models are emerging as the preference for cancer research due to increased clinical relevance over subcutaneous mouse models. In the current study, we developed orthotopic pancreatic cancer xe...

This study presents experimental test results of a compressed natural gas (CNG) direct injection (DI) engine, which has been developed by modifying a single cylinder diesel engine. The major modifications are (a) modification of components such as cylinder head, piston etc. and (b) development and deployment of electronic fuel injection system and (c) installation of a capacitive discharge igni...

Large-eddy simulations (LES) coupled with a partially-stirred reactor model and finite-rate chemistry are carried out to investigate the effects of n-heptane injection timing on methanol fueled dual-fuel (DF) combustion. Methanol is premixed air in constant volume chamber (T=1000 K, ρ=14.8 kg/m3) form homogeneous mixture (equivalence ratio ϕm 0.3). Liquid fuel provided from high pressure inject...

In the current study, a 0D/1D engine model built in commercial code GT-Suite was coupled with Electronic Control Unit (ECU) created Simulink environment, aiming to more accurately predict interaction of and aftertreatment system (ATS) operating parameters, both during steady-state transient maneuvers. After detailed validation based on extensive experimental data from heavy-duty diesel Internal...

The number of tropical cyclones observed in the Australian region (south of equator; 105-160~ has apparently declined since the start of reliable (satellite) observations in the 1969/70 season. However, the number of more intense cyclones (with minimum pressures dropping to 970 hPa or lower) has increased slightly. The numbers of weak (minimum pressures not dropping below 990 hPa) and moderate ...
