Numerical simulation of hydrodynamic properties of Alex type gliders
Simulation of an underwater glider to investigate the effect of angle of attack on the hydrodynamic coefficients such as lift, drag, and torque. Due to the vital role of these coefficients in designing the controllers of a glider and to obtain an accurate result, this simulation has been studied at a range of operating velocities. The total length of the underwater glider with two wings is 900 ...
متن کاملNumerical investigations on the stability of flame balls
The paper is concerned with the numerical simulation of two– and three–dimensional flame balls. In the two–dimensional case we use a Galerkin–type discretization in an adaptive basis of orthogonal wavelets. Therewith the solution is represented by means of a reduced basis being adapted in each time step. For the three–dimensional simulations we employ a classical Fourier pseudospectral method i...
متن کاملNumerical Simulation of a Laboratory-Scale Turbulent Slot Flame
We present three-dimensional, time-dependent simulations of the flowfield of a laboratory-scale slot burner. The simulations are performed using an adaptive time-dependent low Mach number combustion algorithm based on a second-order projection formulation that conserves both species mass and total enthalpy. The methodology incorporates detailed chemical kinetics and a mixture model for differen...
متن کاملNumerical Simulation of a Premixed Turbulent V-Flame
Turbulent premixed combustion is a major active research topic in combustion science. A number of computational studies have focused on idealized configurations to aid in interpreting flame dynamics observed in the laboratory, including one-dimensional strained flames, two-dimensional vortex/flame interactions and limited three-dimensional direct numerical simulations. In this paper, we present...
متن کاملDirect Numerical Simulation of Nonpremixed Flame Extinction by Water Spray
The interaction of turbulent nonpremixed flames with fine water spray is studied using direct numerical simulations (DNS) with detailed chemistry. The study is of practical importance in fire safety devices that operate in the mist regime, as well as an inexpensive temperature control mechanism for gas turbines. The implemented computational methods for the Lagrangian particle-in-cell spray dro...
