The ship powering performance can be predicted based on model tests or simulations. However, differences exist between the full-scale and extrapolated data. Therefore, research simulation has important scientific significance engineering value. This study used REGAL general cargo vessel to perform resistance self-propulsion simulations for various grid numbers, time step sizes, wall Y+ values c...

In hybrid simulation, the structure is divided into numerical and physical substructures to achieve more accurate responses in comparison to a full computational analysis. As a consequence of the lack of test facilities and actuators, and the budget limitation, only a few substructures can be modeled experimentally, whereas the others have to be modeled numerically. In this paper, a new hybrid ...

for large and complex reacting systems, computational efficiency becomes a critical issue in process simulation, optimization and model-based control. mechanism simplification is often a necessity to improve computational speed. we present a novel approach to simplification of reaction networks that formulates the model reduction problem as an optimization problem and solves it using genetic al...

Smoke management system is proposed for life safety in karaoke establishments. Arguments are supported by simulating different scenarios with a two-layer zone model. A typical room-corridor structure of a karaoke establishment is selected. Different ventilation arrangements are considered. With careful design such as adequate extraction rates, smoke layer in the corridor can be kept at high lev...
