With the increase of resources of supercomputer system, handing and visualization of huge DNS data of turbulent combustion become more important. In this paper, current state in the data handing is discussed based on the state of art DNS. Even though the speed of internet is improved, data transfer time of DNS data from the remote supercomputer is still enormous, which prevents active researches. The effective utilization of scientific visualization is also prevented by the data transfer time. To resolve this issue, cloud-type data analysis center will be required to use expensive huge DNS database effectively. As for the visualization of DNS data, several defects in visualization without mature consideration are described especially for contour surfaces and volume rendering. The inappropriate applications of these techniques result in misreading of physics. The developments in acquisition system and laser cause similar problems in experimental researches. The practical realizations of 3D technique and virtual reality may contribute further developments in turbulent combustion researches though the scientific visualization.
