  • Airborne sand and dust soiling of solar collecting mirrors 
    Sansom, Christopher L.; Almond, Heather; King, Peter; Endaya, Essam; Bouaichaoui, Sofiane (AIP, 2017-06-27)
    The reflectance of solar collecting mirrors can be significantly reduced by sand and dust soiling, particularly in arid environments. Larger airborne sand and dust particles can also cause damage by erosion, again reducing ...
  • Alignment measurements uncertainties for large assemblies using probabilistic analysis techniques. 
    Doytchinov, Iordan (2017-12)
    Big science and ambitious industrial projects continually push forward with technical requirements beyond the grasp of conventional engineering techniques. Example of those are ultra-high precision requirements in the field ...
  • Contact cleaning of polymer film solar reflectors 
    Sansom, Christopher L.; Fernández-García, Aránzazu; Sutter, Florian; Almond, Heather; King, Helen (AIP Publishing, 2016-01-31)
    This paper describes the accelerated ageing of polymer film reflecting surfaces under the conditions to be found during contact cleaning of Concentrating Solar Power (CSP) collectors in the presence of dust and sand ...
  • The design and modification of a parabolic trough system for the hydrothermal liquefaction of waste 
    Almond, Heather; Tonnellier, Xavier; Sansom, Christopher L.; Pearce, Matt; Sengar, Namrata (AIP Publishing, 2019-07-26)
    We describe the design of a small-scale parabolic trough with a high-pressure absorber bundle to convert microalgae into bio-oil. The “proof-of-concept” system uses an existing Global CSP solar captor, with its reflectance ...
  • The design of dust barriers to reduce collector mirror soiling in CSP plants 
    Sansom, Christopher L.; King, Peter; Fernandez-Garcia, Aranzazu; Almond, Heather; Kayani, Talib; Boujjat, Houssamme (American Institute of Physics, 2018-11-08)
    In this work we investigate, design, and evaluate a number of dust barrier designs that would be appropriate to reduce soiling of glass mirror solar collectors in the solar field of an existing CSP plant. The principal ...
  • Design Principles for FES Concept Development 
    Dakin, Samuel (Cranfield University, 2013-10)
    A variety of pathologies can cause injury to the spinal cord and hinder movement. A range of equipment is available to help spinal injury sufferers move their affected limbs. One method of rehabilitation is functional ...
  • Impact of dust on electrical power output of solar PV modules in North-East, Nigeria 
    Abdulkarim, Hauwa Talatu; Sansom, Christopher L.; Patchigolla, Kumar; Almond, Heather; Karim, Mounia (Niger State College of Education, 2022-05-30)
    The impact of dust on the solar PV modules deserves more attention. North-eastern Nigeria has high potential of solar irradiance but it is proned to dust accumulation. This paper therefore, investigated the impact of dust ...
  • Investigation of pre and post plating surface roughness of electroless nickel phosphorus coated substrate for diamond turning application 
    Xia, Peter; Almond, Heather; Impey, Susan A. (European Society for Precision Engineering and Nanotechnology, 2016-06-30)
    In an overarching project to reduce the number of defects found in electroless nickel phosphorus alloy (EN-P) coatings on large diamond-turned components used in the next generation of reel-to-reel (R2R) printing stations, ...
  • Investigation of the Thermo-hydraulic performance of a roughened Parabolic trough collector 
    Allauddin, Usman; Rafique, Muhammad U.; Malik, Osama; Rashid, Osama; Waseem, Ashir; King, Peter; Karim, Mounia; Almond, Heather (Elsevier, 2022-10-28)
    Parabolic trough collectors (PTC) are an already established technology set to prove its competitiveness. Recently, a lot of research is ongoing to further enhance the thermal performance of PTC systems. Computational Fluid ...
  • Low-profile and wearable energy harvester based on plucked piezoelectric cantilevers 
    Pozzi, Michele; Almond, Heather; Leighton, Glenn J. T.; Moriarty, Roy J. (Society of Photo-optical Instrumentation Engineers, 2015-05-21)
    The Pizzicato Energy Harvester (EH) introduced the technique of frequency up-conversion to piezoelectric EHs wearable on the lateral side of the knee-joint. The operation principle is to pluck the piezoelectric bimorphs ...
  • Microfabrication processing of titanium for biomedical devices with reduced impact on the environment 
    Gastol, Dominika A. (Cranfield University, 2012-09)
    This thesis presents research on a novel method of microfabrication of titanium (Ti) biomedical devices. The aim of the work was to develop a commercial process to fabricate Ti in a more environmentally friendly manner ...
  • Predicting the effects of sand erosion on collector surfaces in CSP plants 
    Sansom, Christopher L.; Comley, Paul; King, Peter; Almond, Heather; Atkinson, C.; Endaya, E. (Elsevier, 2015-06-05)
    This paper presents a methodology to predict the optical performance and physical topography of the glass collector surfaces of any given CSP plant in the presence of sand and dust storms, providing that local climate ...
  • Soiling and cleaning of polymer film solar reflectors 
    Sansom, Christopher L.; Fernández-García, Aránzazu; Sutter, Florian; Almond, Heather; King, Peter; Martínez-Arcos, Lucía (MDPI, 2016-11-29)
    This paper describes the accelerated ageing of commercially available silvered polymer film by contact cleaning using brushes and water in the presence of soiling created by dust and sand particles. These conditions represent ...
