Micromobility and the Next Infrastructure Wave

EPR202402210/04/2024

US transportation infrastructure is dominated by the automobile form factor. Alternative modalities of movement, such as bikes, golf carts, and other micromobility options, have existed but are decidedly at a lower tier of importance. Even pedestrian access ways are not overly emphasized in the US transportation system. This lack of prioritization matches the reality that the vast majority of people and commerce moves through the motor vehicle infrastructure, with micromobility sitting in the periphery. Additionally, given the current lack of commercial applications, there are limited direct fee-based funding mechanisms connected to micromobility form factors. Micromobility and the Next Infrastructure Wave discusses how recent technological innovations in electrification, e-commerce, and autonomy are enabling a new class of micromobility devices which offer palpable value to consumers and enable significant commercial applications. Unlike the past, these micromobility devices now have

Controlling Aircraft—From Humans to Autonomous Systems: Rise of the Machines

EPR202402009/25/2024

Paris, June 18, 1914: Crowds gathered at the “Concours de la Sécurité en Aéroplane” to witness 21-year-old Lawrence Sperry demonstrate his newly invented gyroscopic stabilizer. With his hands in the air, the device flew his Curtiss C-2 flying boat. Only a decade after the Wright brothers’ initial flight, the first n “autopilot” made its public debut. As impressive as this public demonstration was, it was merely a humble, although spectacular moment of foreshadowing. Even today—110 years later—the process of automating aspects of flight has not yet fully concluded, leading to deteriorating insight into the automatic behavior of aircraft systems, and even the waning of human instincts and intuition. Controlling Aircraft—From Humans to Autonomous Systems: Rise of the Machines covers the distancing of humans from their flying machines through more than a century-long process of “assisting” systems introduction, the positive and negative consequences of this process, and mitigation

The Role of Hybrid Vehicles in a Net-zero Transport System

EPR202402109/25/2024

As the world looks to net-zero emissions goals, hybrid electric vehicles may play an increasingly important role. For passenger electric vehicles (EVs) that predominantly make short journeys but occasionally need to make longer trips, electrofuel range extension may be more cost effective than either hydrogen or rapid charging. Micro gas turbines and catalytic combustion show significant potential to deliver low-cost, low-maintenance, lightweight engines with virtually no emissions, and hydrocarbon consuming solid oxide fuel cells show even greater potential in these areas. Aditioanlly, sodium-ion batteries for EVs, dispatachable vehicle-to-grid power and buffering, and variable intermittent renewable energy could also play key roles. The Role of Hybrid Vehicles in a Net-zero Transport System explores the costs, considerations, and challenges facing these technologies.

Investigating Contact Pressure in Combustion Seal Designs for Injectors: Experimental and Finite Element Analysis

03-18-01-0007

11/22/2024

This study investigated the contact pressure distribution of three combustion seal designs for fuel injectors using both experimental techniques and finite element analysis (FEA). The designs tested included the baseline seal (Design #1), a conical seal (Design #2), and the current production seal (Design #3). In phase 1, a 2D axisymmetric FEA was conducted under worst-case torque conditions (67.8 Nm) to simulate contact pressure, with an axial load of 10 kN and combustion pressure of 21.3 MPa applied to the injector assembly. Phase 2 employed Fuji films to measure the pressure distribution at higher torques (89.5 and 115.2 Nm) in a more realistic scenario, incorporating challenges such as misalignment and eccentric loading. During this phase, Fuji film shearing was a significant challenge, complicating the accurate assessment of pressure profiles. Design #1 failed to maintain the minimum threshold contact pressure of 70 MPa over a 1 mm length, leading to potential leakage. Design #2

Effect of Water Injection Parameters on Upper Load Limit and Nitrogen Oxides Emissions of a Homogeneous Charge Compression Ignition Engine—A Computational Fluid Dynamics Study

03-18-01-0006

11/22/2024

Direct water injection inside the cylinder is a promising technique to enhance the upper load limit and reduce nitrogen oxides emissions. The advantage of water injection depends on the percentage of water evaporated inside the cylinder. The percentage of water evaporation depends upon the water injection parameters. Hence, a computational fluid dynamics analysis is done to determine the effect of water injection temperature, water spray cone angle, nozzle hole diameter, and number of nozzle holes on in-cylinder distribution and percentage of water evaporation, engine performance, and emissions of a homogeneous charge compression ignition engine. This analysis considers water injection temperature from 295 K to 385 K, water spray cone angle from 8° to 24°, nozzle hole diameter from 0.14 mm to 0.205 mm, and number of nozzle holes from 4 to 7. The computational fluid dynamics models used are validated from the available experimental data in the literature for the engine considered. Here

Computational Modeling of Aerodynamic Design Trends for a Production SUV Subjected to Incremental Design Changes: Roof Spoiler and Underbody Geometry

15-18-01-0006

11/21/2024

In this work, we evaluated computational fluid dynamics (CFD) methods for predicting the design trends in flow around a mass-production luxury sport utility vehicle (SUV) subjected to incremental design changes via spoiler and underbody combinations. We compared Reynolds-averaged Navier–Stokes (RANS) using several turbulence models and a delayed detached eddy simulation (DDES) to experimental measurements from a 40% scale wind tunnel test model at matched full-scale Reynolds number. Regardless of turbulence model, RANS was unable to consistently reproduce the design trends in drag from wind tunnel data. This inability of RANS to reproduce the drag trends stemmed from inaccurate base pressure predictions for each vehicle configuration brought on by highly separated flow within the vehicle wake. When taking A-B design trends, many of these errors compounded together to form design trends that did not reflect those measured in experiments. On the other hand, DDES proved to be more
