Machine learning for the prediction of the local drag forces and heat transfer rates in turbulent flows past rough surfaces

Turbulent flows past rough surfaces can create substantial energy losses in engineering equipment. During the last decades, developing accurate correlations to predict the thermal and hydrodynamic behavior of rough surfaces has proven to be a difficult challenge. In this work, we develop a convolutional neural network architecture to perform...

The influence of thermal contact resistance on the thermal history in laser-assisted fiber placement

The temperature history during the laser assisted fiber placement (LAFP) process is very important since it significantly influences the final quality of the structure. Air pockets between subsequent plies, caused by the lack of intimate contact, act as insulators and reduce the through-thickness heat transfer. This phenomenon is commonly...

Efficient methodology of roll load prediction on 2D bodies in nonlinear flows

Generating an absorbing boundary conditions for combined wave-current sumulations

On the elastic beam-fluid interaction based on structural mode shapes

Generating and absorbing boundary conditions for combined wave-current simulations

The CFD simulation tool ComFLOW is extended to investigate the characteristics of wave motions in the presence of steady uniform currents. Initially, the inflow boundary is the superposition of waves and current. Effect of the latter on the former is resolved by solving Navier-Stokes equations within the domain as a next step. A Generating and...

Emergence of Integrated Water Resources Management: Measuring implementation in Vietnam

Recently, the changes in laws and regulations, such as the revised Law on Water Resources in 2012, have sought to provide a legal framework for the internationally recognized practices of Integrated Water Resources Management (IWRM) in Vietnam. With IWRM being a novel approach for Vietnam, it would be interesting to evaluate how well water...

Matrix damage healing in fibre reinforced composite materials containing woven-in shape memory alloy wires

Continuous fiber reinforced composite materials are susceptible to delamination upon impact. Shape Memory Alloy (SMA) wires can be used to assist the healing of damage employing various known or new healing methodologies. Upon a local heating stimulus the contracting action of pre-strained wires, oriented parallel to the out-of-plane direction...
