Performance Analysis of Microthrusters Based on Coupled Thermal-Fluid Modeling and Simulation

Gas flow and performance characteristics of a high-temperature micro-electronically machined systems (MEMS)-based thruster are studied using a coupled thermal-fluid analysis. The material thermal response governed by the transient-heat-conduction equation is obtained by the finite element method. The low–Reynolds number gas flow in the microthruster is modeled by the direct simulation Monte Car...

Hydrodynamics and Control in Thermal-fluid Networks

by Walfre Franco Theoretical, numerical and experimental studies of hydraulic, thermal and control aspects in fluid networks are presented. First, a one-dimensional differentialalgebraic nonlinear model, based on first principles, representing the time-dependent behavior in networks is developed. A thermal-hydraulic analysis of a small network with three common control strategies for heating an...

Effect of Thermal Environment on Vibration Analysis of Partially Cracked Thin Isotropic Plate Submerged in Fluid

Based on a non classical plate theory, an analytical model is proposed for the first time to analyze free vibration problem of partially cracked thin isotropic submerged plate in the presence of thermal environment. The governing equation for the cracked plate is derived using the Kirchhoff’s thin plate theory and the modified couple stress theory. The crack terms are formulated using simplifie...
