  • Numerical simulation of piston leakage over hermetic reciprocating compressors behavior. 

    Rigola Serrano, Joaquim; Pérez Segarra, Carlos David; Oliva Llena, Asensio (2009-09-07)
    Conference lecture
    Open Access
    Instantaneous flow leakage between piston and cylinder is numerically evaluated. Reynolds equation is solved to calculate the pressure leakage distribution through the piston in the compressor. Piston movement inside the ...

  • Sliding mode anti-windup strategy for mass flow-rate regulation of compressors with rate-limited motors 

    Eldigair, Yousif; Kunusch, Cristian; Ocampo-Martínez, Carlos; Camocardi, Pablo (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    In this paper, the control of the mass flow-rate for a centrifugal compressor is discussed. The compressor is driven by a rate-limited actuating motor. To avoid integral windup, a sliding mode control (SMC) based anti-windup ...
  • Uncertainty of optical measurement for high pressure compressor airfoils 

    Ramírez Molero, Cristian (Universitat Politècnica de Catalunya, 2015-12-22)
    Bachelor thesis
    Restricted access - author's decision
    The study of compressor blades is very interesting in quality control and inspection checks. The performance of the engine is meaningful affected by the compressor, where the blades are deteriorated due to entry of different ...
  • Vapor Compression System Modelica Library for Aircraft ECS 

    Ablanque Mejía, Nicolás; Torras Ortiz, Santiago; Oliet Casasayas, Carles; Rigola Serrano, Joaquim; Pérez Segarra, Carlos David (Purdue University, 2018)
    Conference report
    Restricted access - publisher's policy
    This work presents a Modelica library aimed to simulate vapor compression systems at both steady and transient conditions. The simulation of these specific systems is particularly challenging ...
