Centre d’innovació i Tecnologia BARCELONATECH


Heat and Mass Transfer Technological Center

CTTC focuses its activities on heat and mass transfer with generic applications in production technologies, energy and environmental technologies, as well as ICTs. CTTC has a registered patent.

The centre has two main areas of expertise:

Basic research

The centre is involved with mathematical formulation, numerical resolution and experimental validation of heat and mass transfer phenomena. This includes natural and forced convection, turbulence modelling, combustion, two-phase flow, solid-liquid phase change, radiation, porous media, computational fluid dynamics and heat transfer (CFD&HT), aerodynamics, and high-performance computing (numerical algorithms, solvers and parallel computing).

Industrial applied research

• Cooling (compression, absorption, compressors)
• HVAC (environmental design, ventilation, spread of contaminants)
• Active and passive solar systems (solar collectors with transparent insulating surfaces, glass uilding façades)
• High-temperature thermal solar energy
• Heat exchangers (radiators, condensers and evaporators, burners)
• Energy accumulation with phase-change materials
• Cooling  
• Air conditioning in the car and aeronautical industries o Aerodynamics

The centre has worked with the following industries:

  • New storage systems for concentrated solar power

    The Heat and Mass Transfer Technology Center (CTTC UPC) is coordinating the KIC InnoEnergy project on thermal energy storage (TES) systems for concentrated solar power (CSP), to reduce such system’s high capital and maintenance costs, develop advanced analytical engineering tools and propose the best, most innovative solutions.
    CTTC UPC has completed the beta version of two codes (STES and LTES), which are two innovative simulation tools for in-depth thermal and fluid analysis of storage systems for sensitive and latent heat. The codes can be used for i) advanced simulation analysis in relatively short computation times, ii) simulation of a wide range of storage systems (double tank, thermocline, etc.) iii) the analysis of different modes of operation of a plant, iv) special treatment of latent heat storage systems via encapsulated phase change materials, and v) economic analysis of energy stores to obtain minimum investment and operating costs.
