The RNG κ-ε turbulence model derived by Yakhot and Orszag (1986) based on the Renormalization
Group theory has been modified and applied to variable-density engine flows in the …

A temperature wall function was derived for variable-density turbulent flows that are commonly
found in internal combustion engines. Thermodynamic variations of gas density and the …

An integrated numerical model has been developed for diesel engine computations based
on the KIVA-II code. The model incorporates a modified RNG k-ε turbulence model, a 'wave' …

Engine experiments have shown that with high-pressure multiple injections (two or more
injection pulses per power cycle), the soot-NOx trade-off curves of a diesel engine can be …

A sheet spray model is proposed to study the atomization and breakup processes of hollow-cone
fuel sprays resulting from pressure-swirl injectors which have potential for use in direct-…

In this work, the commercially available diesel fuel (Bu00), butanol(20%)–diesel(80%) (by
vol.) (Bu20), butanol(30%)–diesel(70%) (Bu30), and butanol(40%)–diesel (60%) (Bu40) fuels …

Purpose To obtain the treatment parameters of internally cooled microwave antenna and to
evaluate the feasibility of ultrasound-guided percutaneous microwave ablation (MWA) for …

Purpose To retrospectively evaluate the effectiveness and safety of ultrasound (US)-guided
percutaneous microwave ablation (MWA) in the treatment of hepatocellular carcinoma (HCC…

Compared with microwave ablation (MWA), percutaneous radiofrequency ablation (RFA) and
laser ablation (LA) have been recommended as minimally invasive treatments for patients …

Background The diagnosis performance of B-mode ultrasound (US) for focal liver lesions (FLLs)
is relatively limited. We aimed to develop a deep convolutional neural network of US (…
