The purpose of this study is to develop numerical analysis algorithm, which is being able to analyze the compressible flow by Meshless (or Gridless) method. This paper includes Meshless Method on 2-D steady inviscid compressible flow and numerical analysis results of it. The Meshless Method has two aspects. :1) Automatic point generation technique, 2) Numerical analysis scheme. The method applies to an analysis of flow around cylinder depending on a variety of flow velocities. And then it is conducted comparative analysis by a program which is based on Finite Volume Method (FVM) for confirmation of the efficiency, accuracy and convergence.

The purpose of this study is to develop a new Meshless Method to solve 2-D compressible flow problems numerically. This paper includes a revised Least Square method that improves robustness compared with its original version by removing excessive numerical oscillation which occurs when points are randomly distributed. Numerical analyses of hypersonic flow over a blunt body were carried out using the method, then robustness, accuracy and convergence of their results were compared with those obtained from the original method.

A basic study was conducted to predict the internal thermal environment of an aircraft cruising at hypersonic speed. A numerical solver was developed using a meshless method to analyze the conjugate heat transfer of structures and cooling systems. Developed solver was validated comparing with a few analytic solutions for simple shapes. The solvers result was also verified with that from ABAQUS commercial solver for a 3-dimensional shape. In addition, Analysis of heat transfer including cooling channels confirmed that the heat capacity was preserved over time.
