Overview of Research for Prediction of Aerodynamic Heating Environment During a Super-Orbital Reentry Flight of MUSES-C Reentry Capsule
The aerodynamic heating environment with ablation injection and the mass loss rate of the ablator under the superorbital re-entry condition of the MUSES-C sample return capsule are numerically studied by solving the viscous shockIayer (VSL) equations with the nonequilibrium chemistry of both the air and the ablation gas. The boundary conditions at the ablator surface are formulated by consideri...

در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
RADIATION-ABLATION COUPLING FOR CAPSULE REENTRY HEATING VIA SIMULATION and EXPANSION TUBE INVESTIGATIONS
A capsule entering a planetary atmosphere at hypersonic speeds experiences high levels of radiative heating. Furthermore, coupling between the ablation products from the surface of the vehicle and the high temperature gas can have a major effect on the head load experienced by the vehicle. This paper discusses a collaborative project aimed at better characterising the flow processes involved. A...
متن کاملRobust Controller Design Based-on Aerodynamic Load Simulator Identification Driven by PMSM for Hardware-in-the-Loop Simulations
Aerodynamic load simulators generate the required time varying load to test the actuator’s performance in the laboratory. Electric Load Simulator (ELS) as one of variety of the dynamic load simulators should follows the rotation of the Under Test Actuator (UTA) and applies the desired torque to UTA’s rotor at the same time. In such a situation, a very large torque is imposed to the ELS from the...
متن کاملApplication of Homotopy Perturbation Method to One-dimensional Transient Single-phase EM Heating Model
Thermal recovery involves well-known processes such as steam injection (cyclic steam stimulation, steam drive, and steam-assisted gravity drainage), in situ combustion, and a more recent technique that consists of heating the reservoir with electrical energy. When high frequency is used for heating, it is called electromagnetic (EM) heating. The applications of EM heating for heavy-oil reservoi...
