“…But in later work [18,19] air bubbles and water drops are simulated using SPH, and their realism is complete. Kim et al [16] represented the flow of dispersed bubbles using a stochastic solver, but their method still has a limited ability to deal with the collision, merger and overlapping of particles. Rasmussen et al [22] used a hybrid method to control fluids for photorealistic effects.…”

Controlling shapes is a challenging problem in a multi-phase fluid simulation. Bubble particles enable the details of air bubbles to be represented within a simulation based on an Euler grid. We control the target shapes of bubbles by the gradient vectors of the signed distance field and attraction forces associated with control particles. Our hybrid approach enables to simulate physically plausible movements of bubbles while preserving the details of a target shape. Furthermore, we control the paths of moving bubbles using user-defined curves and the shape of an air bubbles by drag force. An accurate model of the drag force near the fluid surface means that bubbles have realistic ellipsoidal shapes.

“…Similar to (Kück et al, 2002), the particles are modeled as spheres which do no not change their shape. By coupling the bubble particles to a low resolution grid, millions of air particles can be simulated efficiently as shown in (Kim et al, 2010). However, in these models the interaction of particles is often neglected.…”

We present a physically-based multiphase model for simulating water and air bubbles with Smoothed Particle Hydrodynamics (SPH). Since the high density ratio of air and water is problematic for existing SPH solvers, we compute the density and pressure forces of both phases separately. The two-way coupling is computed according to the velocity field. The proposed model is capable of simulating the complex bubble flow, e. g. path instability, deformation and merging of bubbles and volume-dependent buoyancy. Furthermore, we present a velocity-based heuristic for generating bubbles in regions where air is likely trapped. Thereby, bubbles are generated on the fly, without explicitly simulating the air phase surrounding the liquid. Instead of deleting the bubbles when they reach the surface, we employ a simple foam model. By incorporating our model into the predictive-corrective SPH method, large time steps can be used. Thus, we can simulate scenarios of high resolution where the size of the bubbles is small in comparison to the liquid volume.

“…Frank et al [16] captured small visual detail with an octree data structure. Impressive effects of bubbles [8][9][10][11][12] ,gases [6] , smoke [4,28] , fluid [1,7,17,[29][30][31][32][33][34][35] , fire [14] , explosion [15] were generated. The above devoted to free flows' realistic effects.…”

“…Realistic effects of fluids' free flows have obtained, such as curling smoke [1][2][3][4][5][6][7] , bubbles [8][9][10][11][12] , sparkling fire [13][14][15] and splashing water [16][17][18] . In addition, animators want to get controlled fluid animations and desired artistic effects by controlling the fluid's flowing path or the target shapes.…”

We present a new method to produce smoke animations. By adding some forces, we efficiently controlled the smoke's target shape and kept smoke alive. Given an arbitrary object's shape represented by a geometric model, our method can generate an animation in which smoke flows out somewhere and quickly forms the shape. It looks like a cloud of moving smoke that fundamentally maintains the shape and fluid-like behavior. By adding two control forces to the physics-based free flow, the shape can be controlled well while smoke flowing. In our system, the free flow and the shape-controlled flow can be easily switched to each other. The additional computation to controlling the shape is negligible compared with the free flow.
