Web1 de set. de 1995 · Abstract. A data base of more than 10,000 critical heat flux (CHF) data points has been compiled and analyzed. Two regimes of CHF are observed which will be referred to as the high CHF regime and the low CHF regime. In the high CHF regime, for pressures less than 110 bar, CHF (q {sub c}) is a determined by local conditions and is … Webregion, where flux-dependent high fouling rates can be observed. Critical and threshold fluxes were measured by adopting the pressure cycle protocol [25]. Once the critical and threshold flux values were obtained, this data was used as input for a batch membrane process optimization method developed previously by Stoller et al. [26–35]. 2. greenburgh town park https://borensteinweb.com
