Sensitivity analysis of the dynamic response of an electronic fuel injector regarding fuel properties and operating conditions
Electronic fuel injectors play an indispensable role in High Pressure Common Rail (HPCR) fuel injection systems and interest numerous researchers to improve their performance. This paper investigates the sensitivity of three fuel properties (the fuel density, bulk modulus and absolute viscosity) to the valve opening/closing delay and the valve opening/closing time.
Performance of diﬀerent optimization concepts for reactive ﬂow systems based on combined CFD and response surface methods
Optimization of reactive flow systems, e.g. coal and biomass combustion, gasification or partial oxidation, is usually a multi-parameter problem, while geometry configurations (e.g. reactor dimensions, burner dimensions) and operating conditions (e.g. fuel mass flow, reactor temperature, cooling capability) mainly determine the process efficiency and profitability.
Field Analysis and Multi-objective Design Optimization of E-Core Transverse-Flux Permanent Magnet Linear Motor
Linear motor can drive linear load directly without the rotary-to-linear conversion as needed for its counterpart rotary motor, which have the advantages of high acceleration, high precision and high operating life. Transverse-flux permanent magnet linear motor (TFPMLM) enjoys the additional merits resulting from the transverse-flux structure, such as high force density, high fault-tolerant ability and electromagnetic decoupling. However, the TFPMLM always features a complicate structure and suffers from large magnetic flux leakage. nalyzing the motor efficiently and accurately is one of the key factors for motor’s optimal design.
A methodology for performance robustness assessment of low-energy
Uncertainties in building operation and external factors such as occupant behavior, climate change, policy changes etc. impact building performance, resulting in possible performance deviation during operation compared to the predicted performance in the design phase. The probability of occurrences of these uncertainties are usually unknown and hence, scenarios are essential to assess the performance robustness of buildings.
Optimizing Seat Belt and Airbag Designs for Rear Seat Occupant Protection in Frontal Crashes
Recent field data have shown that the occupant protection in vehicle rear seats failed to keep pace with advances in the front seats likely due to the lack of advanced safety technologies. The objective of this study was to optimize advanced restraint systems for protecting rear seat occupants with a range of body sizes under different frontal crash pulses.
