First, as an extension of the development of IB-LBM, two different forms of IBM is introduced. The second focus is to evaluate the discrete lattice effect by the contribution of the body force into IB-LBM for various forcing methods. The aforementioned IB-LBMs are designed to enhance the capability of LBM for isothermal problems only, whereas many engineering problems exhibit thermal phenomena. Thus the third focus is to provide a basis for developing IB-thermal LBM. The fourth focus of this dissertation is to apply the IB-LBM with DF/FD (Direct Forcing/Fictitious Domain) method to a practical problem related to a moving body. As an example, the motion of a circular cylinder freely falling in a narrow channel was studied numerically.</span></p>
