Research Area

Rayleigh-Bénard convection (RBC) is a kind of natural convection. Study the convection caused by the temperature difference between the upper and lower walls in the channel. Especially, when particles are added to the RBC, it can be said that ‘the cooler in the industrial field’ and ‘the movement of dust in nature’ are applied to us. The main method to solve the problem is the pseudo spectral method.

This simulation study aims to understand the behavior of particles. The final goal is to interpret particles as a cluster and apply them to natural phenomena and industries.

Turbulent heat transfer is important in various fields such as nuclear reactors, gas turbines and the diffusion of pollutants in urban air, so it is necessary to understand the related physical phenomena correctly. These physical phenomena are nonlinear and complex, so that we use deep learning, which can detect nonlinear relations. As an example, we constructed a convolutional neural network(CNN) that predict turbulent heat transfer using wall shear stress or pressure in turbulent channel flow. We will show that deep learning can help us to analyze complex physical phenomena of turbulence.

Suspended particles in a turbulent flow can be observed in a nature phenomenon found atmosphere, ocean and a lot of industrial applications, many of which are making air pollution, water pollution such as environmental issues and engineering problems. Thus it is very important to expect behavior of the suspended particles.

I have been studying Isotorpic turbulence and homogeneous shear turbulence. Using direct numerical simulation (DNS). I am trying to explain behavior of suspended particles in homogeneous shear turbulent or isotropic turbulent.

The motion of particles in turbulence is often seen in air and water flows and also occurs in many engineering application. Because a solid particle is generally modeled as a sphere, it is important to understand the flow over a sphere. Solid particles in a flow both translate and rotate simultaneously. In particle laden turbulence, the rotation in the streamwise or transverse direction may be induced by inter-particle interactions. Therefore, it is important to understand the effect of rotation on the flow.

The characteristics of flow over a sphere depend significantly on the direction of rotation. One is the transverse direction, where the axis of rotation is orthogonal to that of translation. the other is the streamwise direction, where the rotational direction is the same as that of translation.

The importance of aerosols in our environment are now increasing more than ever before. Espeically, in east Asia including South Korea, tiny dust such as PM2.5 and PM10 become huge issue now. I’m studying how to predict these aerosols well using machine learning techniques.
