Improved Dynamic Reliability Model for Hydraulic Design

Improved reagent delivery using hydraulic fracturing during enhanced reductive dechlorination

In-situ remedial strategies that involve the injection of a remedial fluid offer much promise for cost-effectively treating groundwater contaminants such as chlorinated solvent compounds, nitrated explosives, and perchlorate. The successful implementation of many in-situ remediation projects is dependant on the ability to develop an efficient and effective system for the delivery of the necessa...

Towards an Improved Model for Predicting Hydraulic Turbine Efficiency

Field performance testing of hydraulic turbines is undertaken to define the head-power-discharge relationship, which identify the turbine’s peak operating point. This relationship is essential for the efficient operation of a hydraulic turbine. Unfortunately, in some cases it is not feasible to field test turbines due to time, budgetary, or other constraints. Gordon (2001) proposed a method of ...

Improved Space Heating in Smart Residential Buildings by Applying Dynamic Hydraulic Balancing

Through the hydraulic balancing of heating systems, significant energy savings in residential buildings can be achieved. These savings refer to (primary) heating energy, as well as to (secondary) electric energy for the supporting building services. This paper addresses the use of KNXtechnology and networks (Smart Buildings) in multi-storey residential buildings to ensure a dynamic adaption of ...

Transient Response of Hydraulic Engine Mount to a Realistic Excitation: Improved Non-Linear Models and Validation

Competing linear, quasi-linear and non-linear hydraulic mount formulations of fixed and free decoupler types are comparatively evaluated for transient responses. First, features of the realistic excitation conditions are addressed. For instance, the mean load itself may vary with time, and several sinusoidal or transient excitations may be simultaneously present. Second, a multi-staged top cham...
