Computational Fluid Dynamics
Understanding and predicting physical phenomena is vital in modern engineering and scientific fields. Our research lab focuses on analyzing and predicting fluid flow and heat transfer phenomena with high accuracy by combining advanced numerical methods and parallel computing technologies. Specifically, we use Computational Fluid Dynamics (CFD) techniques to study a wide range of physical problems, from larger-scale phenomena like micro-urban climate to extreme conditions involving high Rayleigh numbers and gas turbine engine nozzles. Below are the main research areas of our lab:
Micro-Urban Climate Studies
Our lab conducts research on various thermal and flow phenomena that occur within cities. Cities are highly sensitive to climate change and environmental issues, and urban heat island effects or wind path formations at the micro-scale have a significant impact on urban planning and infrastructure design. To address these challenges, we use CFD to model and simulate the heat transfer and fluid flow phenomena occurring in urban environments. We combine large-scale urban data with climate models to perform simulations and seek optimization methods to improve heat transfer efficiency within cities.
Simulation of Flow and Heat Transfer in Energy Systems Under Extreme Conditions
We also investigate fluid flow and heat transfer phenomena under extreme conditions, such as high Rayleigh numbers, high temperatures, and high pressures. For example, the heat transfer inside gas turbine engine nozzles is critical for turbine performance and efficiency. As gas turbine engines operate under extreme conditions, accurate numerical analysis and simulation are essential. Our lab uses CFD to analyze physical phenomena in these harsh environments and validates the accuracy of the models through comparison with experimental data.
Particle Behavior and Multiphase Flow Simulations
The behavior of particles associated with fluid flow is an important research topic in many industrial applications. For instance, fuel particle combustion or aerosol distribution plays a significant role in aerospace engine and environmental engineering. Our lab develops models to simulate particle behavior and analyzes it using CFD simulations. We focus on the interaction between particles and fluids, heat transfer, and collision phenomena, addressing multiphase flow problems with advanced algorithms.
Development of High-Accurate/High-Efficient Numerical Methods for Solving Thermal and Flow Systems
Our lab continuously develops new methods and algorithms to achieve high-accuracy and high-efficiency in numerical simulations. This is crucial for solving complex problems such as unsteady flow and turbulence, particularly in extreme environments with parallel computing. We focus on enhancing the accuracy and efficiency of existing methods, developing high-order numerical schemes for precise analysis of complex boundary layer flows, ensuring computational stability, and improving overall solution quality
Our lab conducts in-depth research on a wide range of physical phenomena and develops new methods for high-accuracy CFD-based simulations by combining numerical analysis and parallel computing technologies. From micro-urban climate studies to extreme conditions such as high Rayleigh numbers, particle behavior, and multiphase flow, we cover a diverse array of research areas. Through theoretical analysis and experimental validation, we contribute to solving real-world problems.
Looking forward, our lab will continue to explore new research topics and further develop CFD-based numerical methods and parallel computing technologies to provide effective solutions to complex physical problems.
