Low-frequency and low-amplitude unsteady pressure measurement using polymer-type pressure sensitive paint

Nihon Kikai Gakkai ronbunshu, 2015
Pressure sensitive paint (PSP) using poly(TMSP) as a polymer binder has high pressure sensitivity for low gauge pressure conditions observed in low-speed flows, which is important for research and development in mechanical engineering fields.

Combustion stability, RGF and pressure referencing effect on HRR for a high compression ratio SI engine with natural gas lean mixtures

Case Studies in Thermal Engineering
The knocking and heat release based on cylinder pressure trace is a widespread practice in combustion diagnostic for conventional SI engines. The accuracy depends on quality of measured in-cylinder pressure, thermodynamic models and parameters feeding ...

Temperature State of the Last Cascades of Low Pressure Cylinders of Heat Turbines in Low Flow Rate Modes

NTU "KhPI" Bulletin: Power and heat engineering processes and equipment, 2018
Operation of high-power turbines during the power grid regulation results in that the last cascades of low pressure section are switched over to the power consumption mode which results in additional energy losses. It is especially related to the heat turbines in which the operation modes are regulated by the rotary regulating orifice in the range of ...

Effective Bulk Modulus in Low-Pressure Pump-Controlled Hydraulic Cylinders

Actuators
In this paper, the effective bulk modulus of pump-controlled hydraulic cylinders is studied in the context of linear time-invariant modeling and control. Using an experimental test-rig, the minimum expected value of the effective bulk modulus is identified, and its impact on stability and achievable performance under feedback control is analyzed.

Effect of internal and external EGR on cyclic variability and emissions of a spark ignition two-stroke cycle gasoline engine

Journal of Mechanical Engineering and Sciences, 2017
Conventional two-stroke cycle engine suffers from typical drawbacks including lower combustion efficiency and excessive emissions of uHC and CO which are largely due to low in-cylinder average charge temperature at low load and speed regions of engine ...

Investigation of diesel pre-injection effects on combustion and emission characteristics in a small-displacement ammonia/diesel dual-fuel engine

Fuel Processing Technology
As a zero‑carbon fuel, ammonia is characterized by a high ignition temperature and slow laminar flame speed. Ammonia/diesel dual-fuel (ADDF) mode effectively improves ammonia combustion characteristics.

High Vibration Phenomena due to Cylinder Explosion Pressure of Low-speed Diesel Engine with 7 Cylinders installed on Land

Transactions of the Korean Society for Noise and Vibration Engineering, 2007
A 7K60MC-S low speed diesel engine in a power plant has frequently experienced high vibration since the unit completed construction works. Up to date, no fundamental vibration solutions were reached. Hence, several vibration tests and analyses were conducted to identify the root cause of this high vibration and to suggest the optimal countermeasures ...
