    “desired outcome.” Express this in terms of some measurable property of the system at the end (temperature
    (of what, where?), extent of reaction, etc.).
    2 – Type of chemical process unit
    – reactor, heater/cooler, separator, etc.
    – batch, semibatch, steady state flow, unsteady state flow, etc. – indicate number of feeds (NF),
    number of product streams (NP), and whether or not there is an initial charge
    3 – Secondary processes that occur within the device, and where they occur
    – heat transfer (what kind? Where? Driven by what? Resisted by what? – answer for each
    process that occurs)
    – mass transfer (same questions as for heat transfer – answer for each process that occurs)
    4 – Inputs and outputs
    – mass and energy, and for each, say
    o is it fed as an initial charge, continuous flow, or pulse
    o source of all inputs; destination of all outputs

    – one or more labeled boxes, indicating type of unit (written inside), constants (e.g. T, P, etc.,
    written on top), and if chemical reactor write out reaction (written below)
    – straight unbroken arrows to indicate flow of material
    – straight dashed arrows to indicate one or more pulses of material
    – jagged unbroken arrows to indicate flow of energy
    – jagged dashed arrows to indicate one or more pulses of energy
    – “source” and “disposal” units for all mass and energy inputs and outputs, depicted in each case as
    a box with a question mark (?) and some words explaining what it is.

    desired end point? Don’t forget to include a discussion of what happens with time.
    – Include a discussion of any relevant and/or interesting design features that promote the
    occurrence or efficiency of each aspect of these processes. Insert these comments in ALL
    CAPS in the appropriate place in the text.
    7 – Answer the following:
    – What hardware factors influence the outcome (materials of construction, various size
    parameters or dimensions, proximity of various parts of the unit to each other or to the
    processed material, surface-to-volume ratio considerations, etc.)? Explain for each case.
    – What operating conditions influence the outcome (initial conditions of the unit and/or the
    inputs, T, P, specific mass or energy flow rates, time of operation, etc.)? Explain for each case.
    8 – What aspects of the process can and should be controlled at the source (e.g. temperature, flow rates of any
    inputs, pressure in the unit, run time, etc.). Include a sensitivity analysis of the outcome (and state which
    outcome you’re analyzing) with respect to each of the controlled variables.

  • “Design and Optimization of a Hybrid Parabolic Dish System for Efficient Solar Stirling Engine Power Generation and Thermal Storage”

    To
    address the challenges of high energy prices and network losses, decentralized
    power generation has become essential. Stirling engines, known for their
    remarkable efficiency, offer an economically viable solution by harnessing
    solar energy, which is not suitable for internal combustion engines. Solar
    Stirling engines have the potential to be commercialized and utilized for
    decentralized electricity generation on a small to medium scale. A critical
    aspect of setting up an efficient solar Stirling engine system is the selection
    and design of the collector. This research aims to develop a novel hybrid parabolic
    dish system integrated with a Stirling engine and thermal storage. The
    installation of this hybrid design is complex and has been divided into three
    main sections: (a) the parabolic Stirling system (2m2), (b) the
    parabolic thermal receiver system (6m2), and (c) the phase-change
    materials thermal storage system that connects both systems. An in-depth study
    has been conducted on a meticulously designed 50-watt solar parabolic collector
    optimized for Stirling engines, with the incorporation of optical energy
    storage and thorough thermal analysis. In this setup, solar energy is
    concentrated and directed towards a fluid-filled pipe through a mirror
    arrangement. Solidworks software was employed to determine collector
    parameters, considering geographic, temporal, and environmental conditions,
    fluid inlet temperature, and other relevant factors. The results demonstrate
    that the Stirling engine exhibits oscillating performance in response to
    temperature fluctuations. Testing confirms that the prototype model achieved a
    net output power of up to 50 W at a temperature of 330 ℃, effectively storing
    energy and extending production capabilities until midnight. While initial
    experiments yielded unsatisfactory production power, the integration of an
    additional 4 hours of operation with the thermal control system significantly
    improved performance.
