“…Calculations for adiabatic annular flow pressure gradients (Delil, 1991), according to the equations presented above, confirm (Fig. 5) the pressure drops over an adiabatic section determined experimentally during low-gravity aircraft flights with a R114 system (Chen et al, 1991).…”

The paper deals with heat and mass transfer research issues related to the development of spacecraft active thermal control systems, more specifically development of two-phase heat transport system technology. It focuses on design and development supporting theoretical work: the thermal/ gravitational scaling of two-phase heat transport systems, including the aspects of gravity level dependent two-phase flow pattern mapping and condensation.

“…It makes possible the expression of a wide range of macroscopic flows which are ultimately representative of similar molecular states. With its meso-scopic definition through the lattice Bhatnagar-Gross-Krook (BGK) model it also shows exact conservation properties (Bhatnagar 1954;Chen et al 1991). On the other hand, despite its microscopic foundation, the method is easy to implement, flexible towards additional physics, and advantageous for parallelization.…”

Bone is comprised of an enormously hierarchical construction that promotes transportation of necessary fluids and solids, guaranteeing accurate function and growth. Bone remodeling is a combined process of bone creation and destruction. A number of mathematical models have been developed for the balanced and imbalanced bone remodeling. A brief overview regarding mathematical modeling of bone remodeling is provided. The Lattice Boltzmann method (LBM) has widely been implemented in CFD simulations, and it is becoming more suitable in the application of image processing amongst several others. Mainly, the LBM simulates the communication between synthetic particles dispersed in a lattice. Canaliculi and tortuous channels that have more or less roughly circular structure link among oval bodies identified as lacunae, and are vital to the function of bone. As there is a lack of equipment to inspect flow in channels on the order of measure of canaliculi, so the use of computational methods are more advantageous to give perceptivities into the nature of the flows. In this article, the computational fluid dynamics analysis is descried, using the Lattice Boltzmann method, to examine the result of the microscopic surface roughness of the canalicular wall, which is formed by collagen fibrils, on the flow profiles in the pericellular space.
