Described are computer-related techniques for determining rotation direction of an axial fan for use in fluid flow simulations. The techniques involve receiving by a computer processing system digital data of a three dimensional representation of an axial fan having plural fan blade, determining by the computer processing system from the data of three dimensional representation of the axial fan, at least a single centerline of a single blade of the axial fan from a two dimensional projection of the axial fan, and calculating by the computer processing system based on the initial valve of fan rotation, an actual value of fan rotational direction.

Disclosed are techniques for determining shroud size of a fan. The techniques receive by a computer processing system digital data of a three-dimensional representation of a shroud of an axial fan, partition the received data into a first partition corresponding to a shroud segment and a second partition corresponding to a fan segment. determine a shroud boundary ring for the shroud segment and a viewing angle of the shroud boundary ring, apply to an image of the first partition a beam shooting process to determine the shroud diameter, determine if there are pixels in the image, which have values that produce signals indicating that the pixels are coincident with portions of the shroud and when signal is detected, calculate the shroud diameter. One aspect includes using the determined should size opening for performing a flow simulation.

Vehicle range projection estimation is implemented by a computer processor of a vehicle having logic executable thereon. The logic receives vehicle range projection data from a remote system over a network as a network service. The vehicle range projection data represents a bounded geographic area in which the vehicle is capable of traveling. The bounded geographic area is defined by global positioning system coordinates attributable to the vehicle in conjunction with an available amount of remaining energy of the vehicle. The logic also stores the vehicle range projection data in a storage device. Upon determining an interruption in a network service has occurred, the logic retrieves stored vehicle range projection data from the storage device, scales the stored vehicle range projection data to a level commensurate with an updated amount of remaining energy of the vehicle, and displays a visual representation of scaled vehicle range projection data in the vehicle.

A vehicle includes a powertrain controller, an energy storage system (ESS), a traction motor, an electrical device such as an HVAC system and/or auxiliary system, and a navigation system. The navigation system generates a recommended eco-route or other travel route. The navigation system receives vehicle state information including a current powertrain state from the controller and a power load value from the device(s), including a state of charge of the ESS. The vehicle state information is used to select between a charge-depleting and a charge-sustaining costing model. The route is generated using the selected model, and then displayed. The navigation system includes a host machine which selects the model and generates the route, and a display screen for displaying the route. A method for generating the route includes receiving the current powertrain state and power load values, and using the state information to select between the charge-depleting and charge-sustaining models.

An energy conversion system includes a first core section, a tank, a flexible structure, and an output coil. The tank contains a volume of fluid having a high magnetic permeability. The flexible structure is fluidly coupled to the tank and movable from a retracted to an extended position in response to the injection of the fluid from the tank. The output coil is in electrical communication with the first core section. A charging station includes a second core section and an input coil. The first and second core sections are in alignment to define an air gap therebetween. The air gap is reduced when the flexible structure is in the extended position within the air gap such that the flexible structure transmits magnetic flux between the second core section and the first core section. The magnetic flux in the first core section induces electrical current in the output coil.
