## Research

### Research Interests

Professor Ma has been engaged in research on interaction between fluid/water-waves and structures since his study for MSc.

The areas covered by his research includes:

• Hydrodynamics of turbines/propellers and wave/current energy devices;

• Hydrodynamics and dynamics of floating and fixed structures used for offshore engineering;

• Responses of Offshore Wind platforms to nonlinear ocean waves;

• Nonlinear wave loadings on marine structures;

• Large scale nonlinear wave dynamics;

• Vortex induced vibration, particularly under combined wave-current conditions;

• New advanced numerical methods, such as QALE-FEM (Quasi Arbitrary Lagrangian-Eulerian Finite Element Method) for modelling fully nonlinear interaction between waves and floating structures, MLPG_R (Meshless Local Petrov-Galerkin method with Rankine source solution) method for modelling interaction between breaking waves and structures, and ESBI (Enhanced Spectral Boundary Integral) method for simulating fully nonlinear waves in random seas on a large temporal and spatial scale.

Recently, his attention has been focused much on multi-scale multi-model simulations of fluid-structure interactions in marine engineering. In this area, he has led the development of several hybrid numerical methods, including the hybrid method combining QALE-FEM and MLPG_R method, the hybrid method combining SPH (Smoothed Particle Hydrodynamics) and MLPG_R method and the hybrid method combining ESBI and Enhanced Nonlinear Schrödinger Equation.

**Offshore engineers to benefit from new wave modelling tool.**Designers of offshore structures could soon benefit from a new software tool under development at City University London. The research team, which has already been awarded more than £100k in funding, claims the tool can model the behaviour of extreme ocean waves more accurately, efficiently and consistently than current technology.

Dr Ma came to the UK in 1992 and started a PhD at University College London in 1994. He joined City in 2002, and was promoted to a senior lecturer position in 2004 and then appointed reader in 2007. The Chang Jiang Scholarship was established in 1998 by China's Ministry of Education and the Li Ka Shing Foundation - a Chinese charitable organisation that supports education and healthcare activities through grants and sponsorships, with the aim of developing Chinese research institutions through the engagement of Chang Jiang scholars. Dr Ma said he appreciated the prospects that the scholarship, to be based at Harbin Engineering University, would give him. "Only a small number of Chinese universities have a chance to host this professorship - around 100, " he said. "I will use this opportunity to extend my collaboration with Chinese researchers in my area."
