We describe a theoretical model of the fluid flow, heat transfer and phase change which occurs when liquid is injected into a fracture bounded by a hot, impermeable rock. We first consider the case of a warm host rock, in which there is no boiling of the water. We then develop the model to describe the case in which the host rock temperature is in excess of the boiling temperature and the water...

The enthalpies of vaporisation, Δ(vap)H(298), of seven ionic liquids (ILs) (four imidazoliums, a pyridinium, a phosphonium and an isouronium) have been determined by temperature programmed desorption using line of sight mass spectrometry. They were: 1-ethyl-3-methylimidazolium bis(pentafluoroethyl)phosphinate, [C(2)C(1)Im][PO(2)(C(2)F(5))(2)]; 1-butyl-3-methylimidazolium octylsulfate, [C(4)C(1)...

This study sought to evaluate the efficacy and safety of photoselective vaporisation (PVP) vs. transurethral resection of the prostate (TURP) for patients with benign prostatic hyperplasia (BPH). Eligible studies were identified from electronic databases (Cochrane Library, PubMed and EMBASE). The database search, quality assessment and data extraction were performed independently by two reviewe...

This article provides a theoretical energy performance and carbon footprint analysis of the hydrofluoroolefin HFO-1234ze(E) mixture R-515B as low global warming potential (GWP) refrigerants to replace hydrofluorocarbon HFC-134a in different heat pump applications. The reference configuration is single-stage cycle with an internal exchanger (IHX). In this way, impact IHX on medium moderately hig...

Alkyl-cyclohexanes can be considered as suitable model compounds to understand the thermochemistry of aromatic and their hydrogenated counterparts discussed Liquid Organic Hydrogen Carrier systems. Thermochemical measurements on these hydrogen-rich are thwarted by complications due 99.9 % purity limitation sample size specific methods. However, data vaporisation formation enthalpies necessary o...

Ethylene glycol (EG) produced from biomass is a promising candidate for several new applications. In this paper, EG derivatives such as mono- and di-tert-butyl ethers are considered. However, accurate thermodynamic data essential to optimise the technology of direct tert-butyl ether synthesis reaction or reverse process isobutene release. The aim work measure vapour pressures combustion energie...

Metal additive manufacturing is promising for designing advanced metallic parts of complex geometries. The challenge lies in process control on melt flow dynamics, alloy mixing and vapour mass loss, which significantly vital the final quality. A high-fidelity thermal-solutal-fluid modelling approach including accurate tracking surface shape, thermo-capillary dynamics vaporisation has been devel...

OBJECTIVE To compare the perioperative morbidity and early follow-up after diode laser vaporisation of the prostate (LVP) and its modification, diode laser under cold irrigation (LUCI) in patients with symptomatic benign prostatic hyperplasia, as the main disadvantages of LVP are the postoperative pain, dysuria and storage urinary symptoms. PATIENTS AND METHODS This was a single-centre prospe...

Abstract: The paper reports on the development and simulation of a physiological model relating to Depth of Anaesthesia via Mean Arterial Pressure (MAP) measurements using the anaesthetic drug isoflurane. Isoflurane is an anaesthetic gas normally administered through a vaporiser-based system which was widely reported to be unreliable and unsuitable for precision driving. Hence, in this study we...
