3D MULTIDISCIPLINARY AUTOMATED DESIGN OPTIMIZATION TOOLBOX FOR WIND TURBINE BLADES

Sagimbayev, Sagi; Kylyshbek, Yestay; Batay, Sagidolla; Zhao, Yong; Fok, Sai; Soo Lee, Teh (MDPI AG, 2021-03-26)

This paper presents two novel automated optimization approaches. The first one proposes a framework to optimize wind turbine blades by integrating multidisciplinary 3D parametric modeling, a physics-based optimization ...
A Comparative Analysis of Different Turbulence Models for Simulating Complex Turbulent Separated Flows over Cubic Geometries

Praliyev, Nurgeldy; Sarsen, Aydarkhan; Kaishubayeva, Nazira; Zhao, Yong; Fok, Sai Cheong; Teh, Soo Lee (IOP PUBLISHING, 2019-10-01)

This study is aimed to compare the performance of four Reynolds Averaged Navier Stokes (RANS) turbulence models in simulating complex flow over two- and three-dimensional (2D and 3D) cubic geometries using experimental ...
EARLY DETECTION OF THE BREAST CANCER USING INFRARED TECHNOLOGY – A COMPREHENSIVE REVIEW

Mashekova, Aigerim; Zhao, Yong; Ng, Eddie Y.K.; Zarikas, Vasilios; Fok, Sai Cheong; Mukhmetov, Olzhas (Thermal Science and Engineering Progress, 2021)

Breast cancer is one of the most common and deadly diseases in women, which can also affect men. Early detection and treatment of this disease can increase the chances of cure. Currently, there are many different ...
An Experimental Framework for Validation of Thermal Modeling for Breast Cancer Detection

Igali, Dastan; Mukhmetov, Olzhas; Zhao, Yong; Fok, Sai Cheong; Teh, Soo Lee (IOP Publishing, 2018-08-01)

In recent years, breast cancer is considered as one of the most predominant causes of death among women in the world. This also accounts for the 11.7 % of the total cancers diagnosed among ladies in Kazakhstan. The survival ...
AN INTEGRATED LABORATORY EXPERIMENT OF REALISTIC DIAGENESIS, PERFORATION AND SAND PRODUCTION USING A LARGE ARTIFICIAL SANDSTONE SPECIMEN

Kozhagulova, Ashirgul; Shabdirova, Ainash; HopMinh, Nguyen; Zhao, Yong (Journal of Rock Mechanics and Geotechnical Engineering, 2020-11-06)

Sand production is, a challenging issue in petroleum industry, mainly associated with weak unconsolidated formations. A novel testing procedure and a new apparatus were developed to conduct an integrated experiment of ...
Investigation of High Lift Force Generation of Dragonfly Wing by a Novel Advanced Mode in Hover

Su, Xiaohui; Zhang, Kaixuan; Zheng, Juan; Zhao, Yong; Han, Ruiqi; Zhang, Jiantao (MDPI, 2020-04-24)

In the paper, a novel flapping mode is presented that can generate high lift force by a dragonfly wing in hover. The new mode, named partial advanced mode (PAM), starts pitching earlier than symmetric rotation during the ...
Numerical Investigations on High Lift Force Generation of 3D Dragonfly Wing during Hovering Motions

Su, Xiaohui; Zhang, Kaixuan; Zheng, Juan; Zhang, Jiantao; Zhao, Yong (IOP PUBLISHING, 2019)

In the paper, a novel numerical method is present to numerically investigate life force generation mechanisms of 3D dragonfly wing during hovering motions. The dynamic mesh which descripts the motion of 3D wing and gird ...
Numerical simulations of triaxial compression tests of cemented sandstone

Rakhimzhanova, Aigerim; Thornton, Colin; Nguyen, Hop Minh; Fok, Sai Cheong; Zhao, Yong (ELSEVIER, 2019-09)

Three-dimensional DEM simulations of triaxial compression tests of cemented sandstone samples have been performed at different values of confining pressure, initial density and bond strength. The results show that with ...
PATIENT/BREAST-SPECIFIC DETECTION OF BREAST TUMOR BASED ON PATIENTS’ THERMOGRAMS, 3D BREAST SCANS, AND REVERSE THERMAL MODELLING

Mukhmetov, Olzhas; Mashekova, Aigerim; Zhao, Yong; Midlenko, Anna; Ng, Eddie Yin Kwee; Fok, Sai (Applied Sciences, 2021-07-16)

Background: Mammography is the preferred method for the diagnosis of breast cancer. However, this diagnostic technique fails to detect tumors of small sizes, and it does not work well for younger patients with high breast ...
A sand production prediction model for weak sandstone reservoir in Kazakhstan

Shabdirova, Ainash; Nguyen, Hop Minh; Zhao, Yong (SCIENCE PRESS, 2019-08)

Weakly consolidated reservoirs are prone to sand production problem, which can lead to equipment damages and environmental issues. The conditions for sand production depend on stresses and properties of rock and fluid. ...
