A Study Into Proton Exchange Membrane Fuel Cell Power And Voltage Prediction Using Artificial Neural Network, Tabbi Wilberforce, Mohammad Biswas
A Study Into Proton Exchange Membrane Fuel Cell Power And Voltage Prediction Using Artificial Neural Network, Tabbi Wilberforce, Mohammad Biswas
Mechanical Engineering Faculty Publications and Presentations
Polymer Electrolyte Membrane fuel cell (PEMFC) uses hydrogen as fuel to generate electricity and by-product water at relatively low operating temperatures, which is environmentally friendly. Since PEMFC performance characteristics are inherently nonlinear and related, predicting the best performance for the different operating conditions is essential to improve the system's efficiency. Thus, modeling using artificial neural networks (ANN) to predict its performance can significantly improve the capabilities of handling multi-variable nonlinear performance of the PEMFC. This paper predicts the electrical performance of a PEMFC stack under various operating conditions. The four input terms for the 5 W PEMFC include anode and …

Dehumidification Performance Of A Variable Speed Heat Pump And A Single Speed Heat Pump With And Without Dehumidification Capabilities In A Warm And Humid Climate, Koukouni P. Kone, Nelson Fumo

Conventional air conditioning systems in houses respond to thermal loads by means of controlling dry-bulb temperature through the thermostat. As part of the process to control temperature, dehumidification is also provided. However, as houses are becoming more efficient, supplemental dehumidification is often necessary for homes located in hot and humid climates to control relative humidity intentionally. This study compared the dehumidification performance of a residential air conditioning system working in three operations modes to emulate three different systems: a system with a variable speed mode, a single-speed system with an enhanced dehumidification mode, and a single-speed system operating in a …

A proton exchange membrane fuel cell (PEMFC) is a more environmentally friendly alternative to deliver electric power in various applications, including in the transportation industry. As PEMFC performance characteristics are inherently nonlinear and involved, the prediction of the performance in a given application for different operating conditions is important in order to optimize the efficiency of the system. Thus, modelling using artificial neural networks (ANNs) to predict its performance can significantly improve the capabilities of handling the multi-variable nonlinear performance of the PEMFC. However, further investigation is needed to develop a dynamic model using ANNs to predict the transient behavior …

Incorporation Of Torsion Springs In A Knee Exoskeleton For Stance Phase Correction Of Crouch Gait, Katy Baker Bumbard, Harold Herrington, Chung-Hyun Goh, Alwathiqbellah Ibrahim

Crouch gait is a motor complication that is commonly associated with cerebral palsy, spastic diplegia, stroke, and motor-neurological pathologies, broadly defined as knee flexion in excess of 20° in the gait cycle. Uncorrected crouch gait results in fatigue, joint degradation, and loss of ambulation. Torsion springs have been used in cycling to store energy in the knee flexion to reduce fatigue in the quadriceps during knee extension. SolidWorks was used to design a passive exoskeleton for the knee, incorporating torsion springs of stiffnesses 20,000 N/mm and 30,000 N/mm at the knee joint, to correct four different crouch gaits. OpenSim was …
A Review Of Ductless Mini Split Hvac System, Manoj Bhandari, Nelson Fumo
A Review Of Ductless Mini Split Hvac System, Manoj Bhandari, Nelson Fumo
Mechanical Engineering Faculty Publications and Presentations
Although a conventional ducted system is the HVAC system used by most of the household in the United States, the ductless mini split system is gaining popularity in the market. The ductless mini split heat pump system consists of an outdoor unit that provides hot or cold refrigerant into a house to one or more wall- or ceiling-mounted indoor fan units. Ductless mini splits can have several advantages over conventional systems including improved thermal comfort, performance, and energy saving. There have been several studies and research in the field of ductless mini splits to learn about the advantages and disadvantages …

Characterizing The Effect Of Adding Boron Nitride Nanotubes On The Mechanical Properties Of Electrospun Polymer Nanocomposite Microfibers Mesh, Ohood Alsmairat, Nael Barakat
Mechanical Engineering Faculty Publications and Presentations
Electrospun fibrous meshes have a variety of applications such as filtration, drug delivery, energy storage, and engineered tissues due to their high surface area to mass ratio. Therefore, understanding the mechanical properties of these continuously evolving meshes is critical to expand and improve their performance. In this study, the effect of adding Boron Nitride Nanotube (BNNT) to Polymethylmethacrylate (PMMA) composite meshes on the mechanical properties of the polymer is studied. Electrospinning is used to fabricate microfiber meshes of PMMA and BNNT-PMMA. The fabricated meshes are tested experimentally with a uniaxial tensile tester. In addition, a theoretical model is introduced to …
