Characterization of a Computational Fluid Dynamics Thermocouple Model Subjected to Stochastic Environmental Forcing Using Moment Based Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With increasing requirements for model validation when comparing computational and experimental results, there is a need to incorporate detailed representations of measurement devices within the computational simulations. ...
Modeling Liquid Film Evaporation in a Wetted Wall Bioaerosol Sampling Cyclone
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The wetted wall bioaerosol sampling cyclone (WWC) is a complex multiphase flow device which collects and concentrates dilute bioaerosols into liquid samples for biological analysis (McFarland et al., 2009, “Wetted Wall ...
A Modified Directional Flame Thermometer: Development, Calibration, and Uncertainty Quantification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The directional flame thermometer (DFT) is a robust device used to measure heat fluxes in harsh environments such as fire scenarios but is large when compared to other standard heat flux measurement devices. To better ...
Experimental and Modeling Uncertainty Considerations for Determining the First Item Ignited in a Compartment Using a Bayesian Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fire scene reconstruction and determining the fire evolution (i.e., item-to-item ignition events) using the postfire compartment is an extremely difficult task because of the time-integrated nature of the observed damages. ...
Applications of Heat Transfer Fundamentals to Fire Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fire industry relies on fire engineers and scientists to develop materials and technologies used to either resist, detect, or suppress fire. While combustion processes are the drivers for what might be considered to ...
Use of a Quasi-Steady Ablation Model for Design Sensitivity With Uncertainty Propagation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sensitivity analysis and design calculations are often best performed using low-order models. This work details work done on adding complementary pieces to a low-order, quasi-steady-state ablation model to facilitate ...
